Hi,
Does anyone have any details on how write precompensation is implemented
on MFM-formatted floppy disks?
I've been reading through the description in various disk controller
datasheets, but they're as clear as mud - to the point where most only
state that an EARLY or LATE signal is generated, not how those signals
are generated.
Reason I ask is, I'm trying to write a disc with a DiscFerret, but
without precompensation they're unreadable... :(
Thanks,
