ABSTRACT:
The periodic component of a timing mark position error of a self-servo write pattern on a disk of a disk drive is determined based on measurements that are made of the timing mark position error at selected radial track locations. The determined periodic component of the timing mark position error is then removed based on the radial location on the disk.
