ABSTRACT:
Methods, servo controllers, disk drives, and computer program products are provided for adapting compensation for repeatable runout (RRO) of sectors of a disk in a disk drive. RRO of a plurality of sectors of the disk is compensated. A status of whether the RRO compensation has been adapted is tracked for at least some of the sectors of the disk, and corresponding records are formed based on the statuses. The RRO compensation of the tracked sectors is selectively adapted or not adapted based on the records.
