It sounded like David has already done that, and has

track data. That's what my "just software" program expects as input.
I should clarify: not a conversion of the analog track data into the encoded
bits, but digitizing the magnetic flux waveforms at a rate that provides
about 15-30 samples per cycle. The software then finds the peaks (or
zero-crossings), derives the clock when necessary, and decodes the bits.
