Yes, that is what you do in practice. Although I have a bunch of alignment
disks for 5.25" 48tpi and 96tpi (and I guess for 8", too), you don't need
them for pure track alignment. I mean, the drive was once good. I can't
see how a solid drive can get out of alignment without physical impact.
The CBM floppy drives seem to a case of cheap drive mechanics. But I guess
that comes from the missing track 0 sensor, thus the head carrier
physically hits the chassis, and this can cause dealignment.
I also know the cats eye patterns etc. from disk drive alignment packs
(e.g. RK05 alignment cartridge). But do I _need_ them for track alignment?
