I did some digging and I don't have any schematics scanned for Maxtor.
Are there any patent numbers on the drive? It may be worth digging around
for Maxtor patents from the mid-80's.

That drive has a dedicated servo surface (thus the odd number of
heads). Not sure there's any concept of microstepping in that

The Seagate ST-4096 is also a servo drive and has the ability to move
the heads a partial track for read error recovery. I assume its adding an
offset into the servo loop to vary the head position.
