Solid State Tape   (+5)  [vote for, against]
For your discerning caveman

Take an audio cassette cartridge, and remove the tape. Stripe the rollers' outer circumference with an alternating color pattern. Replace the tape with an icb containing storage, logic, and ad/da convertors. Provide 4 (or even 8!) discreet parallel interfaces to the storage at the point where the tape traditionally meets the read and record heads in an analog tape deck (like tracks). As the deck rotates the color bands, read this motion to indicate forward or backward movement through storage. Apply power by way of a wire dangling out from under the deck cover; said wire could house receptacle for a battery and a usb interface for transfer.

Now you can record on your tape deck without all that silly tape hiss! Maybe I will just get another gerbil... *sigh*

Generate power by the turning of the tape reels.

Ingenius. Pointless. Bun.

Cassette-shaped .mp3 players were popular a few years ago, [link] but the Rewind/FF interface may be novel. +

Coloured stripes are so last century. Use a hall effect sensor, or just a tacho wheel for all the accuracy you'll need.

[phoenix], I considered the power from the turning of the wheels, but I'm not sure you could consistently get enough juice in a small enough package.

Thanks, [wags]. That's sort of my mantra.
