ABSTRACT:
A method of selecting a zone lay-out of a hard disk drive on the basis of head/recording medium performance, which method includes (a) setting a reference position of each of the magnetic heads to measure the head performance, and a reference value of the head performance at the reference position; (b) making a disk drive by selecting a zone lay-out corresponding to the reference value of the head performance; (c) measuring an error rate of all zones of the disk drive by using the selected zone lay-out; and (d) when the measured error rate does not satisfy the reference value, selecting another zone lay-out of another disk drive of lower capacity, and performing the next test on that disk drive.
