Encoding Data for Audio Tape?

Kris_J asks: "I've recently purchased and installed an audio cassette deck for my PC. It makes recording to and from tape particularly painless, but I'm looking for some funky other stuff to try. Along the lines of my new old SuperDisk FD32MB that can store 32MB on a normal 1.44MB floppy, and my Cuttle Cart that can load Atari 2600 games from encoded audio I'm wondering if there's any program that can encode a file as audio that can survive being recorded to audio tape or compressed as an MP3. I'll worry about 'why' later."

tape yes, mp3 no

MP3 is a lossy compression. If lossy recovery is OK with you, fine. For storage to tape - maybe cwpcm the file after uuencoding it. I can't remember if there's a morse code character for each character used by uuencode.
on a more practical line - send it as straight ascii, using the ham radio interfaces in Linux, through the sound card. decode that with the same interfaces and you're done. Those tools are used to loss, but I'd expect 100% copy on and off tape.

Re:This looks like a pretty cool product.

Okay, long story. It appeared on one of the Gadget blogs I frequent and I tried to get it directly and failed. However, my credit card's loyalty scheme includes something about "Rewards as broad as your imagination" where you can tell them what you want and they'll get it for you. After a month or so Citibank were able to get in contact and have the product shipped to me.

The device itself is quite simple. It's a 5.25" device with a standard power connection. It also has a ribbon cable that runs to a simple adapter that fits in a slot in the case (thought it doesn't plug in like a card) -- from there you connect it to audio in/out and a serial port. Software is seriously basic and I think Windows only, but you can just set a few settings and press a button to have it convert an entire tape, both sides, to an MP3 file. I then cut it up using MP3DirectCut. Just converted an old Vangelis tape yesterday.

So, yeah, it's basically a tape drive with Line In / Line Out and a serial port. However, I'm barely a programmer, just a bit of PHP and SQL, no C, no drivers, no comms, so I'm not up to the task of writing anything myself.

my question

[Zork the Almighty]

Dear Slashdot: I'm looking for a way to store data so that the probability of recovering it is extremely low. I can't just delete the files since my company has a legal obligation to store them, so /dev/null is out of the question. Ideally I'd like some sort of crappy, hacked solution using media which is totally inappropriate and unreliable. I've already tried writing 32MB to 1.44MB floppy disks but that just wasn't bad enough. In your opinion, what is the shittiest data storage technology available ?
