MP3 player in a cassette tape form factor

The idea is to make a typical portable mp3 player in the form factor of a cassette tape. Built-in would be a magnetic head to couple sound directly to a tape player.

This solves the problem of requiring a cassette adapter to go from your mp3 player to your car deck.

It would still have a headphone jack so could be used portably. Would likely require rechargeable built-in batteries only, to be made thin enough. Could still have a display. Cool thing (or idea flaw) would be that the track advance buttons would not always be accessible depending on what type of deck you put it into, so the functions (fwd/back/play/pause) would have to be controlled by sensing the motion of the reel cogs - cool eh?

This idea is technically possible, but even as the "inventor", I don't think there's much of a need/market for it, so I'm just posting it for the sake of mental masturbation.

Looks like a cassette tape; functions like one when you put it into a cassette player. [jutta, Jun 20 2007]

They seem to not exist anymore, so here's a link to an archived version of their site [hippo, Jun 21 2007]

sorry, i'm not a fan of cassettes or fooling with them anyhow. on the other hand, anyone actually remember a-tracks?

// anyone actually remember a-tracks?// No, are they anything like mondegreen 8-tracks?

This is baked, I seached for it a few years ago when I thought of it and it already existed then. I thought there was one here on the bakery too but I can't find it. The only innovations I had was to charge it using the rotation of the spools and have a removable face on a wire that stuck out of the player.

[marklar] - are you thinking of the "RetroPod" (linked)and the RomeMP3 player (linked)?

a-tracks/8-tracks confusion...tee hee hee.

I want to see an implementation of an MP3 player into a large disk-shaped vinyl object that will reproduce accurately on a record player - advanced models will allow for scratching effects.

[zen] Relatively easy to do - you just need to convert the sound into a varying magnetic field which would be detected by the needle pickups.

That's ok for these new fangled record players - I should have been more specific - what I want is an mp3 gramophone record!
-- zen_tom, Jun 21 2007

ok, this would be like a little toy car that tries to go round in a circle as the deck spins or doesn't if you just have a wind-up gramophone and you are lazy. The 'roof' of the car would have a concave vibrating membrane like a speaker but more durable for the needle to sit on. et viola.
