I guess I don't understand this. Single-density FM and double-density MFM
have the same maximum number of flux reversals per unit distance (which is
how the RX02 can write double-density data on a single-density floppy). So
from the magnetic domain perspective, the coating can't really see any
difference between single-density FM and double-density MFM. So what's
the difference, if any, between a disk which is "rated for FM" and one
"rated for MFM"?
