Since this list has a number of people that are very knowledgable on the
subject :
Am i correct in thinking that, given a custom FDC, i could run a modern
1.44 floppy in FM mode, and at much lower data rates i.e. (say 50 KHz.) ?
You;ll have no problem with using FM, but I thought there was a minimum
data rate requirement too.
Certainly the read output will give a fixed-width pulse for every flux
transtion on the media (so don't expect the read data output to
faithfully reproduce the pulses you fed into the write data line, in fact
just the leading edges will be preserved). I had an idea that if the flux
transitions were too far apart then some part of the read chain got
confused, but maybe not.
