ABSTRACT:
In a discrimination mode for discriminating a track density mode of an FDD using a carriage mechanism of the lead screw type, on the basis of a reciprocal seek operation of a magnetic head, when a carriage is moved a seek distance dependent on a track density in a forward seek mode, the drive of the carriage mechanism can reliably be stopped. This realizes a reciprocal seek operation of the head that depends on a track density mode of the FDD. Accordingly, a host computer compares the number of pulses contained in a STEP signal in a forward seek stroke with that in a reverse seek stroke, and reliably discriminate a track density mode of the FDD on the basis of the comparison result.
