In the case of 5.25" "megafloppy"
drives, such as the Drivetek, that
would be almost trivial, once you got into the drive MCU firmware That
Err, yes... That's a big 'onece you get' :-)
is, if the "fine" stepper could move quickly
enough.
I was thinking of the normal stepper-motor posiitoend drives. Many of tha
later onescould step betwene tracks in 6ms. Given tha thr disk takes
200ms to rotate once, it would appaer you proably could wobble the head
fast enough.
Most of the time 2 stpper widnigns are driven on each track. I would
think if you varied the current i nthe 2 windings it was no logner
equaly, the head would be displaced slightly. Wobble siad currents nad
you might be able to ghet the head to do what you need.
