Rotating memory data recovery

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.
