In one embodiment, a disk including a first plurality of tracks each includes first and second servo bursts defining a track reference line, and a second plurality of the first plurality of tracks on the disk each includes third and fourth servo bursts defining a second plurality of different position offsets from the track reference line of the second plurality of tracks. Each of the second plurality of different position offsets being at a different value than any other position offset. The second plurality is no greater than the first plurality. The second plurality of different position offsets are used for linearizing a position error signal.
