No doubt of it.

Why not? Enconding is absolutely unrelated to bit cell width.
EDIT: well, "absolutely unrelated" is a bit exaggerated ; actually only specific encodings allow certain bit densities and for surfaces like floppy the MFM is certainly more suitable (and simple and fast) than GCR. But require faster interface... so one of the GCR family was used previously.

The point is the MSBSYNC usage that is not present (but I really looked at it quickly and I could be wrong)
