ABSTRACT:
A servo track write method is disclosed in which, in a disk drive of a perpendicular magnetic recording system, servo data is written with the use of a single magnetic pole type head of the disk drive itself. In this method, the servo data is recorded on a disk in those servo areas with the use of the single magnetic hole type head mounted on the disk drive. A head mounted as the single magnetic pole type head is position-controlled relative to the servo area by a servo track writer. The servo data is recorded with perpendicular magnetization under a recording magnetic field from the single magnetic pole type head in accordance with the magnetic pole thickness of the single magnetic pole type head.
