ABSTRACT:
A disk drive includes an actuator assembly having a read/write head, a spindle motor, a disk mounted for rotation on the spindle motor, a wedge-to-wedge timer and a sector size selector. The disk includes a recording surface having a plurality of tracks and each track includes a plurality of servo wedges. The recording surface has at least one data sector between circumferentially adjacent servo wedges on each track. The wedge to wedge timer measures the time elapsed between at least two successive detections of circumferentially adjacent servo wedges and outputs a wedge-to-wedge correction signal that is dependent upon the measured elapsed time. The sector size selector outputs a sector size signal that changes according to the wedge-to-wedge correction signal. In turn, the sector size signal determines the size of the next data sector on the recording surface of the disk.
