No.  However, the data sheets for the NEC uPD765, Intel 8271 and 8272, and
Western Digital 1771 and 1791 have a lot of useful information about it.  The

Ah... so, now we know about FM, MFM and GCR. Off topic, but anyone know where to find good info about RLL? (since most modern non-floppy disks use a variant of that)
