Abstract
A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of tracks, wherein each track comprises a plurality of servo sectors. The head is positioned over a first track, and when a first servo sector is processed, a first touchdown metric is evaluated to detect whether the head contacted the disk without evaluating a second touchdown metric. When a second servo sector is processed, the second touchdown metric is evaluated to detect whether the head contacted the disk without evaluating the first touchdown metric.
