Posts: 80From: subsequent to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 02-15-2018 02:19 PM i'm in touch with a person who will assist me read NASA records tapes from the 60s to 70s. This adult has journey studying these type of facts tapes, as he has carried out so earlier than for JPL.
this is able to be an instance of 1 such tape, notwithstanding not the equal mission as I have seen to this point.
Some quick appears on the tapes confirmed Lunar Orbiter, Apollo, Skylab and satellite tv for pc 1/2 inch width and 10.5 inch diameter laptop tape reels. If they get any information out of them, they should be uploaded as public domain to archive.org
under are significant ingredients of a dialog they are having:
Me: today I played part of the tape through an AKAI X201D. I didn't are expecting to get any usable data, maybe a faint sign.
that you can find WAV information and spectrograms here. Test001 via Test003 have been manually moved along the heads. Test004 and test006 had been fed along the heads by the use of the capstan at 3 3/4. Test005 is performed at 7 1/2 inches per 2nd.
Test005 has a continual tone. Test006 is the very starting of the tape, and has weird bursts in the beginning.
Contact: Having finished a couple of these for JPL, i might say that here is a 7-tune 800 BPI NRZI tape. counting on the accurate tape pressure, it could possibly doubtless be study on a 729-equipped 1401. Making experience of the records, despite the fact, is a different story. Early Sixties NASA tapes tended to be 7090/ninety four ones, with later ones, Univac 1100 sequence right up in the course of the early 1980s.
or you can ship it to me and that i'll extract the facts. My contacts at JPL say there are lots of those issues kicking around.
Me: can you any experience out of the sound recordings I have made? What are the short bursts on test006 and the tone on test005.
i would be superb grateful in case you may extract the data. the way to most efficient ship a tape? I ought to ship mine from The Netherlands to your location, which I assume is the usa. Any additional tapes I get I might have shipped directly to you from a seller in america. whatever you need. i do know a lot of people will be excited to seem to be on the recovered data.
Is it possible which you could are trying and get the tape recognized through the individuals at JPL? I did scrub off the upper label to reveal the lower label with some greater assistance.
Contact: No, I don't suppose that I might do anything along with your audio. most likely an examination with a magnetic developer (similar to Kyread) and a low power microscope would check my suppositions. that might at least let you know what number of tracks are involved and define the inter-block spacing, if applicable.
there's a faint chance that these could also be analog telemetry tapes, but a view with a magnetic developer would examine that. youngsters, what i will be able to see of the in part-covered label appears to point out a common digital tape, but the notice on the label that says "audio" is puzzling. were that the case, be sure to be capable of get whatever thing using an audio recorder to play these returned.
i was under the affect that tapes used for analog telemetry lower back within the 60s changed into very diverse from general 10.5" 1/2" tape, however you not ever know.
they're basically digital tapes if you have blocks of facts separated with the aid of about three/4" of erased space. it's average 7 song layout.
finally, a lot of these tapes are basic recertified "scratch tapes" — it is, used tapes again to the scratch pool and run through a certifier (which erases all data). A tape label that specifies contents and the name of the programmer holds out the greatest hope, but even so, within the plenty I've dealt with, about 10% were recertified scratch. NASA, like a lot of government operations, re-used tapes heavily, trimming off tape at the beginning when it wore out and applying a brand new BOT marker. probably the most tapes that I've labored on have a number of hundred feed sacrificed.
loads of these items is blended-structure statistics (some textual content, lots of binary) data that can be very intricate to suss out without the application that created it. for example, here's one of the tapes that I did: in most cases 7094 floating-point information with just a few bits of 7090 BCDIC jumbled together.
Me: in fact cool that you just worked on NASA tapes before, how did that become? and how do the tapes continually grow to be in the 'wild'?
there are lots of unknowns, but with small steps I accept as true with they can figure this out.
I looked around for Kyread, and buying from their website the shipping charge by myself is a hundred and fifty greenbacks. i can purchase magnetic viewing film a great deal more affordable, do you believe it has ample decision to view the tracks?
If it does have analog telemetry, is there a unique class of audio recorder they should play them on? or will any 7 track multi tune recorder do? I don't know if a 1/2 inch 7 music audio recorder exist, 1/2 inch 8 track tape recorders were greater general. nowadays I spooled the tape through my 1/four inch four track stereo recorder again, this time there have been 4 to five diverse frequency tones in the spectogram as an alternative of 1. might it's overlapping tracks?
Is it viable rectifying a tape motives this continual tone? i'll get some NASA tapes soon which have a better knowledge to dangle facts.
Contact: My tapes got here without delay from NASA JPL in Pasadena. I don't own them — and they have been returned after statistics retrieval, along with the records retrieved from them. In other phrases, it's JPL's property, now not mine and i deal with it that manner.
Kyread is nothing greater than 1 to three micron iron particles in a fast-evaporating fluid (it used to be a kind of Freon, however considering the fact that that turned into banned, methyl perfluoroisobutyl ether is used). It is comparatively inert, so it doesn't have an effect on the coating or base cloth. You shake the bottle up and drop a drop of the suspension on the tape and enable the solution to evaporate. considering the fact that the iron particles are so small, that you could visualize very small facets in the tape. With an honest chemistry lab, it is going to now not be tricky to mix a few of this up on your vicinity, assuming that the service liquid is prison in the european.
When I actually have a new tape, except i'm very certain about the content material, here is always the first step. Tapes labeled as 9 track frequently become 7 tune and vice-versa. What are you going to consider, your eyes or some lying label?
The other issue is coaching of the medium. continuously, the system is to "bake" the tape, then run it through a tape cleaning computer. additional remedy may well be crucial, corresponding to lubrication, to get the tape to examine. in spite of everything, you haven't any theory of the storage conditions during the 50 or so years that the tape has been in storage. it be no longer exotic for splicing tape (used to attach leaders) to dry out and let go, so you ought to be prepared for that. BOT and EOT markers in a similar way dry out and fall off...
The tapes you pictured above are certainly records tapes and definitely 7-music (9 track tapes don't continually happen with even parity). however you cannot get your expectations too high. The Apollo program concerned hundreds of subcontractors who generated doubtless tens of lots of tapes. The GE tapes you reveal above may be nothing greater than engine check information — and like such issues, you want a Rosetta stone to interpret it, when you consider that or not it's unlikely that the data will include any clues. before the times of excessive-velocity telecom and massive disk drives, tape become king. Outfits like NASA ordered tapes by means of the truckload.
however, when you are willing to take a shot, i'm inclined to have a go at it.Our dialog endured in deepest and bought fairly technical. i will be able to are attempting to get the tracks visualized on the tape currently with me and am looking into getting it performed on a multitrack 1/2 recorder, whether it is analog telemetry they may get anything.
As for the statistics tapes, my contact will handle these.apollo16uvcMember

The tape arrived today — the pictures don't do it justice(?). The reel is chipped and completely filthy — it looks as if it spent the previous 50 years on the floor of a person's backyard shed.
At this element, it be intricate to tell how an awful lot of the tape is unbroken. here is my plan:
smartly, I unreeled slightly of the tape; I didn't find a BOT marker, so I suspected that the first few meters of the tape are heritage
right here's what I see after I look on the tape:
9-tune, now not 7! If the date on the tape is appropriate, this ability it was produced on an IBM system/360, as basically no person else had working 9 tune drives then. Even in 1965, IBM become delivery the primary S/360s out with 729 7-music drives. It took them awhile to get the bugs out of the 2400 sequence drives.
testing the very starting of this very wrinkled tape suggests statistics on the first few cm, so if there become a frontrunner, or not it's been long long gone.
i may bake and clean the tape and fasten a BOT marker about 3 m in and notice what i can see with my 9-song drives. This can also take a couple of days.apollo16uvcMember

Posts: 80From: subsequent to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 03-17-2018 12:29 PM Two greater tapes have arrived this week, a quick replace beneath:
The 2d set of tapes arrived in respectable kind. initially blush, they appear to be extra swap panel data, however we'll be aware of more later.
not like the final batch that were outfitted with poly "tape hanger" strips, these were in 60s-period 3M complicated styrene cases. That became decent news and unhealthy information. The respectable news is that the cases use a weatherstrip-class rubber foam to seal the edges of both case halves. The dangerous news is that the foam has long past the style of all historic rubber and deteriorated, virtually gluing the case halves collectively. With some coaxing and tough pulling, youngsters, they got here apart. I removed the unhealthy foam in order that this might not be an issue sooner or later.
I baked and cleaned the tapes (1179 turned into a little bit sticky) and did a short run-via of them.
2090 reads completely; no considerations — the information appears plenty like the previous tapes; 132-personality facts of what i'm supposing are change legends. just one single parity error (i will isolate it to a single byte). 14,404 statistics amounting to about 2 MB.
1179 starts off the identical means, but after about 663 blocks, every thing goes to hell. Parity blunders, brief blocks, incomplete data. The only way i will be able to suppose of resurrecting anything else is to effortlessly read without retrying all of the information i will be able to, after which trying to make some experience of the effect. My suspicion is that the tape become saved (for years) near a magnetic box and so grew to be partly erased. physically, the tape is in first-class circumstance; no longer shedding or exhibiting another physical damage.apollo16uvcMember

Posts: 80From: next to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 03-20-2018 eleven:fifty nine AM we are at the moment brainstorming on the foremost approach to digitize 1179. When processing the BCDIC data to ASCII they get mostly rubbish and the occasional readable string.
The most beneficial means can be to read it with none retries and take a look at and make something out of it, this may additionally requirements a firmware hack of the power. The .faucet layout does assist forward and backwards retries nonetheless it reads the equal mistakes every time.

Posts: 80From: next to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 06-07-2018 09:25 AM 4 greater tapes had been despatched and received. This time relating to the Pioneer 10 and/or eleven probes.
The tapes showed up today in a single field. every tape is shrink-wrapped; so far so good.
Judging from the labels, i suspect that here is imaging photopolarimeter (IPP) facts from Pioneer 10 or 11. Neither spacecraft had a real digital camera per se; photos have been built from the IPP statistics. institution of Arizona optical science core changed into the drive in the back of the design and verify of the IPP. The IPP, to my figuring out, operated slightly just like the historic mechanical Baird tv gadget. The IPP had an aperture and changed into spun to create a "scan" pattern, digitized and returned as a little stream of statistics.
due to the fact I've considered papers from 2014 using the normal Pioneer IPP information to verify history radiation, i believe the statistics continues to be very much around.
As to a way to interpret the data on the tapes, they are going to need to see what they get.If they are capable of read them i will be able to try to contact some people which have purchased the different seven tapes and may are attempting to borrow them for records restoration. Updates will observe. apollo16uvcMember

I had a go at the first of the brand new tapes (qk7992h); it's a 800 NRZI 9-tune tape and or not it's EBCDIC on the first couple of records. The tape is set 6MB and generally seems to be binary information. The header mentions that here is may additionally 21, 1978 and consists of the word "VESTA" and interestingly the identify of the person responsible "ZELLNER".

i'm beginning here with the tape QK7992H from NASA within the lot of 4. i suspect that or not it's the most reliable because it's likely the normal.
At any expense, count this as a test handiest — there looks to be only 1 uncorrected parity error in block a hundred thirty.
observe that any text in these is EBCDIC, not ASCII. The records structure seems to be mounted size facts of eighty three (complete) bytes, each checklist starting off with its number in EBCDIC. initial statistics are fully in text; subsequent statistics are binary facts.
as an example, the first actual block (translated from EBCDIC to ASCII) is...

Two Pioneer eleven tapes have arrived, what they recognize now:
The tapes have arrived in good form these days. they're that on the first inspection labeled "1600 bpi," so 9-tune PE density, which is constantly lots greater more reliable than NRZI 800 (7 or 9 tracks).
looking closely on the two tapes that simply arrived, I've found a puzzle. both have labels that point out that they are 7-song 556 BPI. however one additionally has a later label indicating 9-tune 1600 BPI.

take a look at these two extraordinarily certain docs:You won't find a definition of the the genuine switch action table tape layout, however the tape is clearly describing the configuration counsel for the SLCC system.
On page 3-9/three-10 (fifty six within the PDF) of the programmer's manual, it mentions the "Discrete govt":
The Discrete government initiates logging at both computer systems. There are a couple of several types of discrete tables each containing specific information. These tables are:

That sounds lots like their tapes. My wager is that they're the input statistics for the NT98 Discrete Initialization application, which regrettably is rarely described in aspect. If anyone can locate here files, I guess we'd locate what they want there:

Posts: 80From: subsequent to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 12-24-2018 01:12 PM on the grounds that last week I actually have bought four NASA tapes from eBay. it is 1/2 inch tape on a ten.5 inch reel and has 7 tracks. The tapes are recorded with Ampex FR-a hundred and Ampex FR-600 instrumental recorders. On the tapes are analog telemetry signals from satellites, recorded at NASA stations in 1963.
It appears that there are six telemetry tracks, and one voice song.
I won't have have Ampex FR-a hundred or FR-600, and they are very scarce. Nor do I actually have a 1/2 inch eight-music recorder.
What now? There are eight-tune 1/2 sound recorders. The peak difference between eight and 7-tune is so small, I feel you could play a 7-tune tape on an eight-song recorder.
in case you regulate the 8-track head up and down, to align it with one song at a time I consider they can decide upon up a fine sign. I have talked with somebody, and he says the tracks are just analog waveforms. I once performed a 9-track 1/2 tape on a 1/four 4-tune recorder, and i received an unusable however reliable signal.
I and others would definitely recognize it if somebody makes his (or hers) eight-track 1/2 inch recorder accessible. The tapes will need to be shipped from the Netherlands. For this to work, the pinnacle should be adjustable. it will be premiere to use an Ampex FR-100 and FR-600, but I think it be not going that we'll encounter them.
I additionally tried to win an auction of an different desktop tape, however sadly the bids went means out of my price range. The tape was related to this document and have it ship off the Chuck for facts healing. The writing on the tape is as follows:
Identification:Presto (Fortran IV)File I - SourceFile II - BinaryFile III - verify Case

regrettably the vendor of magtape B40968-B4-6-2 prefers no longer to contact the purchaser about my records restoration carrier. I additionally requested if I could just know the identify of the museum, however alas.
(subsequent bit may additionally include some venting)
so far there has been one purchaser, who bought the different six-some thing Pioneer 11 tapes who declined my offer. And two marketers who opt for now not to contact their buyers, in reasonable of damaging company relationships. One lot had been +2500 NASA/IBM punchcards that i think had been used for some kind of Saturn V and LM building. The other lot turned into the Radd tape outlined above.
They claim it could decrease the cost of those items. this is nonsense, in the final three many years NASA and different sources were placing terrabytes of audio, video and photographs on-line. Yet singular slides and tapes still promote for a couple of a whole lot of dollars.
and not contacting the museum is simply ridicules. the only and absolute aim of a museum is to hold an item for future generations and teach americans. If this does not turn up, it may as well now not exist. I do not know about that museum, but most do not have a large funds, and unique mediums like tape are mainly expensive and problematic to digitize. a real shame I may not be in a position to support.
in the end, I simply believe it is unhappy some individuals only see money, and never the event forward of them, and the value to maintain these items for future analysis.
not to conclusion on a sour notice, i would like to thank everyone who volunteered thus far.
i'm also speaking with a dutch fellow about loaning a 1/2 eight-tune tape recorder from him to try and play back the telemetry tapes. i think they might be in a position to at the least take heed to the voice channel (Trk 7).
additionally, here is a colour-photograph recovered from magtape QK7992H.

with the intention to rejoice (nearly) new 12 months, I even have decided to release an unfinished edition of the processed records from Pione-QK7992H accomplished via Hans. There are 12 info on the tape, of which they now have demonstrated six to be photo info, and have decoded them. There are three B/W photographs and three duo-color pictures (file 1, 2, 6, 7, eleven, 12).
As to what is on them, they don't yet understand. in case you know anybody that might help, inform him about me!
As for the six remaining data, they aren't certain what these are. Their ASCII metadata is corresponding to the graphic info, but the statistics is diverse. by processing one of the ultimate information anyway, they get weird patterns that might trace to a few kind of graphic structure, but they don't know!
Hans has separated the binary data from all 12 files from the SIMH file and put every in their own folder. When applicable he converted them to images. each folder is presented with the raw binary records and readable ASCII metadata.
be aware here is unfinished, as some non-graphic data have most effective their metadata provided, not the binary statistics. This should be performed later when Hans has the time. savour!
confidently the satellite tv for pc tapes will arrive within the subsequent two weeks, then I may be in a position to decide their situation, and if they should be baked or now not. however because the SSS should be would becould very well be within the center or end, and never at the start, its going to be elaborate as I cannot unspool the entire tape.
Is there anyone who can try and determine the satellites? This are the sat identifications on the documentation and tapes:
1963 30B1963 14B and 14C?? 63 14A and B6330213 (or) 63302|threei am speaking with someone within the Netherlands who has a number of eight-music 1/2 machines, but has no longer used them for years and doesn't recognize if they work accurately or not. If none work, one can also need to be repaired. i may then mortgage the desktop for my tapes. i will be able to additionally figure out if i can purchase the repaired recorder or no longer, that would be first rate for future projects!
If I setup a crowdfund for the repair would anybody be willing to help fund it?
presently i am digitizing two 1/four inch domestic recordings of Mercury and Gemini news coverage, including John Glen's flight! can be up soon. My Akai X-201D and Revox A77 MK 4 need repairs too however it is an other matter. The Akai X-201D receives a noisy channel after a while (chiefly in the event you turn it off and on) and the Revox A77 has mechanical and relay complications.
Will retain you guys updated!
Have a cheerful and protected new yr. for many discoveries in 2019! — NielsminipciMember

Posts: 80From: subsequent to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 01-12-2019 06:08 PM four satellite tapes have arrived. I have decent and dangerous news; first they look on the first rate:
As you could see in the pictures, the reels and tape are in first rate condition. All reels had been carefully full of normal documentation in an aluminum holder. This holder turned into in two layers of cardboard. The cardboard seems to have a little of water harm, however the tape has remained covered within the holder, which also has no rust. The reel has no scratches and dents.
The tape doesn't odor and looks good. I do not word any mold or rotting. Optically, the tape is clean with little scratching on the playback aspect.
I actually have unspooled part of the tape and that i do not note any Sticky Shed Syndrome, however of course I may only examine the beginning.
Now then, I dared to try to play the tape on my Akai X201D 1/four four-song tape recorder. I did this by using unwinding a piece of the tape and guiding the tape during the tape route guides and capstan. The tape receives pulled in the course of the capstan in another field. With clear gloves, I be certain that the tape runs over the heads at the right pressure.
This turned into successful in itself as a result of I received a number of alerts. through carefully moving the tape up and down, i will are attempting to focal point on 1 tune. additional than this I didn't come.
The bottom sound file are the unique items from a couple of minutes of play on 7-1/2 I.P.S
The tape number on the packing containers and documentation is 3141/2N003. The number on the reel itself is 10786-sixteen-eight.
satellite tv for pc: 1963-014A & B (ERS5)Recorder: FR-100Speed: 15 I.P.SStation name: GFORKSWith this we've proven that whatever thing is on the tape, and it can be picked up with a sound head.
i am speakme to Peter about borrowing an eight-song tape recorder. His Otari MX-5050 eight unit is most wonderful considering it might probably play two speeds, 7/1-2 and 15 I.P.S which is what i want.
After taking a look, and all mechanical features appear to be working. Playback, fastforward/rewind. When he sends a sound from the construct-in tone generator to the recording enter, all VU meters register correctly and there is sound.
however... there is not any sound on playback! its feasible there's nothing on the tape, he will are trying and locate an different one to test once he has the time.
Neither of us have the components, gadget and time to restoration and calibrate this sort of machine. So its doubtless they have to hand it over to a company for repairs and calibration.
And now the dangerous news: Two tapes i tried to play have audio, but two have not! I get no sign, simply as if there became no tape at all. possibly this tape has been erased, or recorded with one more recorder that does not play on my Akai. Or I can not unspool the tape some distance ample.
Will keep you guys posted once there is an replace.apollo16uvcMember
Posts: 80From: subsequent to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 01-13-2019 03:46 PM Given the FR-a hundred and FR-600 recorded alerts on tape as frequency modulation, I count on the digitized indicators would deserve to be de-modulated? I think a timing/reference channel would deserve to be used for this to account for tape velocity fluctuations and coating irregularities.
Any concept whether the telemetry from these forms of sats was analog, or from a digital computing device?
probably the most tapes are from Winkfield, so its likely they were recorded with this desktop.apollo16uvcMember
Posts: 80From: next to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 01-29-2019 09:47 AM I've bought first rate, and awesome information.
First the respectable news, I assembled a small setup to be able to play extra of the tapes on my 1/four inch 4-song recorder. I played the tapes that I up to now turned into afraid had no alerts in any respect, and after a while (eight-10 minutes) they too provide the anticipated signals. thus far I received six tapes, five of which hang alerts.
The extraordinary news I've obtained, is that I even have recorded the reference music in short by way of moving the tape up and down. The reference is a 10Khz tone on course four, as seen on the connected document. pass to (2:35) on the connected .mp3 file. Its exactly 10Khz on the recording.later on when i will be able to make relevant scans of all documentation and cases.
it might be useful if they knew the music geometry of the FR-100, FR-600 and Otari MX-5050 8. They should still be capable of definitely see this on the tape by using a magnetic developer solution. they're very expensive to buy and ship, so I actually have talked with Chuck on how to make it myself. it's quite standard, and he tried it on a floppy disk with decent results and no damage to the facts. With specified macro photos they will determine how well the tracks align. reside tuned!apollo16uvcMember
Posts: 80From: next to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 03-01-2019 05:forty two PM in the meanwhile I even have received five ESA satellite tv for pc tapes, additionally appear to be telemetry.
I even have established out three of the five ESA tapes with a magnetic viewing answer, and all three clearly showed seven tracks just like the NASA tapes. This capability they have not been degaused or overwritten with an audio recorder. The tracks look like raw telemetry, now not laptop tapes. One tape has a label that certainly says it got here from a monitoring station. I suppose they should still be able to digitize these too finally. The tracks are very clear.
The tapes I even have verified are:
And 2d, a video the place I visualize the magnetic tracks on three tapes:
here are some photos of the tracks. I promise i will be able to post a huge archive with certain scans and pictures of all ESA and NASA tapes at present in my possession.
I even have additionally make zip archives for all seven NASA satellite tapes I've obtained to this point. They can be found right here. The seven zip information mentioned here delivery with "Sat-" and may be updated and renamed to later versions when confidently they be capable of digitize the tapes and technique the telemetry.apollo16uvcMember
Posts: 80From: subsequent to LEM, Descartes Highlands, MoonRegistered: Jan 2017posted 03-12-2019 04:eleven PM Some exciting new finds, did they play telemetry?'
remaining week I took the time to play some ESA tapes (1/2 inch 7-track) on my Akai X201D (1/four inch 4-tune) The tapes played:
I made a video the place I play the tapes and demonstrate it on an oscilliscope:
Some spectacular particulars: ESRO 1A has loads of pastime in the beginning, it feels like a reference signal this is being adjusted. There pitch alterations and there are periods of noise. at last they acquire a good sign which is certainly greater complex than an easy sine wave.
ESRO 1A:TD-1 TD-1A loads of new counsel with the intention to take some time to manner.
It seems to me somewhat feasible that this is the received statistics. If they locate files from the imperative satellite with tips about telemetry, may still it's possible to create a application or circuit that processes the signal? A program might convert it to a spreadsheet. How lots volts the battery outputs every 2d for example.
I do not know the rest about it, however the ESA recordings don't appear to be FM-modulated, due to the fact that the sort of wave looks very distinct. The NASA recordings are constantly now not, so curiously AM and FM modulation was no longer general in recordings from this time. The NASA documentation always additionally has "Direct" recordings and never "FM".
i'm hunting for americans who may well be capable of assist with the imperative satellites, and who are extra acquainted with this variety of work.
additionally, have ultimately complete v1.0 of the archive for the NASA satellite tapes.

quote:firstly posted via SpaceAholic:have you ever tried to read tapes from the Apollo Command Module facts Storage equipment? hold a DSE on this conclusion and there is a few hobby in ascertaining if it nevertheless holds mission vox/information. What an amazing artifact! No, I have not tried to digitize anything else like this.
i'm engaged on a couple of tasks to digitize ancient NASA tapes. These range from audio, computing device facts, telemetry statistics to video. along with volunteers we’ve had some splendid discoveries and successes.
I actually have lately used a house-made magnetic viewing solution on a number of tapes to visualize the magnetic tracks. This works, and i changed into in a position to evidently see details in the tracks. This doesn't damage the tape or the facts, i'm the use of the recipe used by using an proprietor of the statistics recovery company. it is truly a mix of carbonyl iron energy and methanol. He has used it on three.5 1.44mb floppy disks without facts loss. After photographs have been taken it will also be removed with a cloth and a few alcohol.
The tracks can turn into so precise, that it will be possible to examine content of the tracks (Vox, direct, FM, AM, frequency). most effective tiny parts over the lenght of the tape (+/- 10cm) are needed, at a couple of random places alongside the reel.
i'm fascinated to understand more about this artifact, and digitize the contents. through the use of a magnetic viewing answer, they are able to examine if there's anything else on the tape, how potent the tracks are, and what form sign could be on the tracks.
For this, respectable lightning and a macro lens or scanner is required, as I actually have observed the most excellent aspect can also be photographed before the solution has dried out. Preferable from a number of diverse angles.
I actually have made two video’s as an academic, one on how to make it, and shows me using it on some NASA satellite tapes to visualize the tracks. they're in dutch, however i will run you via it if you want.
Of path, if you make an answer it is going to first be tried on other tapes to make sure it doesn’t harm the contents. On a VHS, audio or floppy disk for example. provided that you whipe it off with none warping and don’t hurt the case it will be first-rate.
I should be happy to reply any questions. This appears like a fantastic possibility to do some thing grand with such an important artifact.Contact Us | The source for house history & Artifacts
