Digital audio off vinyl?

[[email protected]]

After looking at articles about data cassettes and the Kansas City
standard I heard the Apple I BASIC tapedump on BoingBoing. Does anyone
know if it would be possible to transfer digital audio files to a 12
inch 33.3 RPM record or cassette? Quality is of minimal importance, I
just need to know how to do this and how to successfully retrieve the
data.

I'm sure you can but what would be the point? In fact they do this sorta
thing already for data storage. Tape backup, for data storage, and ADAT, for
digital music, are the most common.

A long time ago in a land far, far away...

One of the Computer Hobbyist magazines distributed software on audio
disks. They were 33-1/3 RPM records pressed into thin mylar sheets,
just like demo records were distributed at that time. I seem to
recall that the data was encoded to audio using the KC standard; all
one had to do is hook up their record player to their KC interface,
and play the data. That's one group that transferred digital files to
audio.

I'm guessing that what you want to do is put MP3 files on a Compact
Cassette so you can listen to them with your antique Walk-Man. Just
play the files on your PC, and run 'line-out' from your sound port to
'line-in' on your cassette deck.

I haven't see a home 'LP' recorder in 30+ years. Any blank you could
find would be way past it's shelf life...

** The KC standard is either 300 or 1200 baud.

A music CD uses 1.4 Mbits /second.

I see a problem.

I don't. Information Society's album Peace & Love Inc. contains a
track of modem tones.

I have that CD, I don't know if this one came out on vinyl.

You're none too clear about what youre trying to achieve. Putting
digital files on audio cassette was standard practice 30 years ago,
but its extremely slow and the failure rate isnt that great. OTOH it
does store well, under the right conditions. Putting it onto discs is
quite low tech if you're wiling to make your own disc cutter. I can't
imagine the point though.

OTOH if you mean data retrieval for real time music decoding &
listening, thats not so easy, and only possible with excessive
difficulty
