Abstract :
A microprocessor on board of a 5 1/4 in floppy disk unit can be used for microstep control of the step motor able to compensate for unavoidable track deformations. The feedback is derived from a special signal recorded at the beginning of each sector. The resulting track following system is very attractive for magnetic peripherals with very high track density (192 tpi). The authors describe the design of the control system and its implementation using a Z80A system
