How do you calibrate that head positioner? What do you measure, etc?
I would ahve thoughtusign a travelling mciroscope to locate the track
position (developed with magnasee) would be a reasoanble way to do that.
Incidentally, does anyone know of a source of 3" (not 3.5") alignment disks?

I would guess floppies were done the same
way as hard drives. They'd write a track and then
sprinkle some liquid ( I suspect like used for
magnaflux ) on it. They use a microscope with a
calibrated position to locate the data.
A good HOBBYIST way to check it.
A manufacturer would use a CASLIBRATED head positioner with
greater accuracy and different head than that of a consumer drive.
