This reminds me of an old hacky product that would let you use cheap VHS tapes as backup storage: https://en.wikipedia.org/wiki/ArVid

You would hit Record on a VCR and the computer data would be encoded as video data on the tape.

People are clever.

Wow, 2GB on a standard tape. For the time, that's incredibly efficient and cheap.

  • Yeah. Video, even old grainy VHS, had a pretty high bandwidth. Even much more so with S-VHS, which did not become super popular though. (I'm actually wondering whether the 2GB figure was for S-VHS, not VHS. Didn't to the math and wouldn't be surprised either way, though.)

    • A normal VHS encodes about 100 million scan lines over 2 hours. 20 bytes per scan line sounds feasible, since there's somewhere around 200-300 'pixels' of luma available in each scan line.

This is old school. When I first wrote code back in the Stone Age we used to store our stuff on cassette tape.

The Alesis ADAT 8 track digital audio recorders used SVHS tapes as the medium - at the end of the day, it's just a spooled magnetic medium, not hugely different conceptually than a hard drive.

That's not really that hacky, audio cassettes were used forever, it's just a tape backup.

I remember a similar solution that was marketed in a German mail order catalogue in late 1990s. It could have been Conrad, but I'm not 100% sure. I recall it being a USB peripheral, though. (Maybe I could find more about it in time...)
