摘要: A method of timing control for servo-data detection in a disk drive. The method includes retrieving a plurality of servo sectors arranged discretely in a circumferential direction of a disk and measuring time intervals between servo sectors. The method also includes determining in which zone of a plurality of preset zones each of the measured time intervals is included. Moreover, the method also includes determining variations in time intervals from the zones of a plurality of previous time intervals, and modifying timing for servo-sector detection if variations in time intervals are within a preset range.
