I believe there are versions for drives with different
head azimuth
angles (the angle between the head gap and a radius of the disk). In my
experience this doesn't seem to matter to much. Yes, there is a head
azimuth test, but azimuth is rarely field-adjustable anyway and I've
never needed to check it. Radial alignment is the important one.
Azimuth was always a depressing thing to scope out on a brand-new,
not-yet-installed drive. Manufacturers didn't seem to set their QA
standards too high in that respect. Micropolis was particularly awful.
