I recorded to tape cassette GDR radio shows on VHF that broadcast code, usually for the GDR "KC 85" 8 bit computer line (U880 processor - Z80 clone).
Funny thing is, you could easily tell from the sounds if the code was assembler or BASIC. The latter was much more orderly and structured.
Problems occurred when someone nearby turned on an electrical device during that transmission, because it was audible and introduced too much of an error and the recording became unusable.
Edit: There is a (small) wikipedia category for this: https://en.wikipedia.org/wiki/Category:Vinyl_data
Your Computer certainly had a few of these in the early 1980s.
One example is documented here: https://magazinesfromthepast.fandom.com/wiki/Your_Computer_V... By the way, you have no idea how exciting and space-age that cover looked in 1982.
It had Atari and Commodore music (as audio) as well as Atari and Commodore software (as data).
Despite the claim on their old page to be the “first use of vinyl for software distribution” they did later acknowledge and reference some prior art in a Slashdot thread: https://slashdot.org/comments.pl?sid=140154&threshold=-1&com...

I wish HN would let you search upvoted comments and submissions, it would revolutionize my life since I can remember previous things I've upvoted, but have no easy way to find any of them. I might sit down one day, and manually export all my liked comments and subscriptions.
