Gareth,

I haven't done this, but here's a wild suggestion: Use a plain vanilla PC
floppy disk controller card. They're very cheap. Just work out the interface
from your microcontroller to the card, which should be well-documented in
the PC hacking literature. Seems to me, it would be a huge bonus if the disk
format stays PC-compatible.
