Patent ID: 7489464

Claim:
A disk drive comprising: (a) a disk; (b) an actuator arm; (c) a head coupled to a distal end of the actuator arm, wherein the head comprises a read element and a write element; (d) a voice coil motor (VCM) for rotating the actuator arm about a pivot to actuate the head radially over the disk; (e) a secondary actuator for adjusting a skew angle for the head; and (f) control circuitry for writing a plurality of servo sectors to the disk to define a plurality of data tracks by: controlling the VCM to move the head radially across the disk; controlling the secondary actuator to achieve a desired skew angle for the head; and using the write element to write the servo sectors to the disk, wherein the control circuitry controls the secondary actuator so that the write element leads the read element from a first diameter of the disk toward a second diameter of the disk across substantially the entire radius of the disk.
