Sure, as long as the drive head was aligned correctly to allow that to
work. AIUI some disc formats have the lower head offset by about half a
track relative to the upper head.
And yes, the DiscFerret does have a side-select output.
Thanks,
This is probably a dumb question and/or one I could Google for, but does
anyone know why the tracks were offset? Was there concern the magnetic
field while writing side 0 would modify the data on side 1 etc.? My
guess would have been that the thickness of the floppy medium was too
great to allow significant interaction between the sides.
