Exercise for the student: implement a constant angular
velocity drive to
read constant linear velocity media
COmmodore floppy drives come close (things like the 8050, 1541, etc).
They're constant angular velocity (only one motor speed), but they change
the data rate (I think 4 or so data rates were used) to pack more sectors
onto the outermost tracks.
