ABSTRACT:
An off-track optimizing apparatus, disk, and method for raising track density of a hard disk drive using a magnetoresistive head. An optimal off-track amount is detected in an initial test process of a hard disk drive, and an additional position detection signal is written into a specific area of a disk. During track follow, the magnetoresistive head is on-tracked in a specific track by using the additional position detection signal.
