Rotating memory data recovery

[John Lawson]

   A simple method of sync would have to be worked out, but, being the 
AnalogGeek(tm) that I am, I'd be tempted to record the bitstreams as 
square-wave audio data to some kind of DAW software... perahps with a 
small amount of roll-off (6dB/oct) coming out of the head amp would limit 
the bandwidth and make the PC or Mac's soundcard happier.....  if you 
could get a 'whole drum after this pulse' (sort of like capturing one 
video frame) sync set up, then you could record each track onto a similar 
parallel track in the DAW....  later this can be 'played back' to recover 
the data....  worst-case is that you have to inspect and slipsyunc 
individual tracks....

  Recording this would be fairly tedious but apart from a high-speed 
multi-track data-logger, It would get the job done.

   Gold-Wave would be a candidate for this, or the 'free' version of 
ProTools....


   Another thought would be to use an external audio osc and power-amp to 
slow down the drum motor and make it easier to record the track pulses and 
index marks...  run the motor at 10 Htz or so.


  Cheers
