   Terrible idea: analog data floppy disk.
   Each period on the disk records a byte.
   Maximum magnetic strength equals 255, minimum magnetic strength equals 0.

   If your noise floor is too high, smaller values cannot be recorded

     @foone Audio floppy disks would be kinda cool

     @mwichary it's been done, as a DIY project!

     @foone Is there enough bandwidth to store a video frame on a single track?

     @fsphil yes. That's been done as a commercial product, in fact

     @uberduck there are no bits, we're measuring analog values

     @foone wouldn't it be if the noise floor is too high you can't record the least significant bits?

     @foone I mean it's terrible if you store data directly, but if you can store a calibration burst and a Reed-Solomon ECC alongside, it might just work...
     ... though 256 levels might be a bit too much, even MLC flash is limited to four levels so far.
