Abstract
A system including a signal generating module and a position control module. The signal generating module generates position error signals based on servo bursts read from a servo region of a track of a disk drive. The servo bursts are read by a head of the disk drive and include first, second, third, and fourth servo bursts. The position control module generates differences between the position error signals and determines a position of the head relative to the track based on (i) a first difference of the differences and (ii) a second difference of the differences. The first difference is based on the first servo burst and the second servo burst. The second difference is based on (i) the third servo burst and (ii) the first servo burst or the second servo burst and is independent of the fourth servo burst.
