ABSTRACT:
A method of servo writing a plurality of servo sectors to a disk of a disk drive to define a plurality of data tracks is disclosed. The disk drive comprises the disk, an actuator arm, a head coupled to a distal end of the actuator arm, wherein the head comprises a read element and a write element. A voice coil motor (VCM) rotates the actuator arm about a pivot to actuate the head radially over the disk, and a secondary actuator adjusts a skew angle for the head while using the write element to write the servo sectors to the disk.
