ABSTRACT:
A sector pulse generating technique for a hard disk drive, includes storing an original time value before defect occurs in the hard disk drive as a first sector pulse value; storing an offset value after the defect occurs as a second sector pulse value; switching the offset value as needed; and comparing the value switched in the above switching step with a reference value and generating a sector pulse as a result of the comparison.
