A disk drive is disclosed comprising a disk comprising a plurality of servo tracks, wherein each servo track comprises a plurality of servo sectors, and a head actuated radially over the disk, wherein the head comprises a read element separated from a write element by a reader/writer gap. The head is positioned over a first servo track, and a clock is synchronized to servo data in first and second servo sectors of the first servo track. A first phase-offset of the clock is measured for the first servo sector, and a second phase-offset of the clock is measured for the second servo sector, wherein the first and second phase-offset correspond to an end of the reader/writer gap at the first servo track. The first and second phase-offset are averaged to generate an average phase-offset for the first servo track. |
