摘要 |
A disk drive is disclosed comprising a disk having servo data defining a plurality of servo tracks. The servo data comprises a preamble, and a plurality of slanted line servo bursts recorded at a tilt angle with respect to the preamble. At least one of the slanted line servo bursts comprises a first polarity along a first segment of the slanted line and a second polarity along a second segment of the slanted line. A position error signal (PES) is generated in response to a phase difference when reading the preamble and the slanted line servo bursts.
