ABSTRACT:
A method of servo writing a disk of a disk drive is disclosed, wherein the disk drive comprising the disk and a head actuated over the disk. Servo sectors are written to define servo tracks from a first diameter of the disk to substantially a middle diameter of the disk, wherein the first diameter is selected from one of the outer and inner diameter of the disk. Servo sectors are then written to define servo tracks from a second diameter of the disk toward the middle diameter of the disk by positioning the head over a current servo track, reading the current servo track to generate a read signal, processing the read signal to detect a previously written servo sector, and if a previously written servo sector is not detected, then writing servo sectors to the current servo track and positioning the head over a next servo track.
