Abstract
A data storage device is disclosed comprising a head actuated over a disk comprising a plurality of servo tracks and a plurality of data tracks defined by the servo tracks. Each servo track is defined by a first set of servo sectors interleaved with a second set of servo sectors, wherein each servo sector comprises a servo burst field. The servo burst field of the first set of servo sectors has a first length and the servo burst field of the second set of servo sectors has a second length longer than the first length. Data is written to a first data track by reading at least one of the second set of servo sectors and skipping the read of at least part of one of the first set of servo sectors, and servoing the head over the first data track in response to reading the second set servo sector.
