ABSTRACT:
A disk drive includes a rotatable data storage disk, a transducer, an actuator, and a controller. The disk includes information and data tracks that are defined thereon. The transducer is configured to read the information from the disk. The actuator is configured to position the transducer relative to the data tracks. The controller is configured to measure timing between particular information on the disk, to estimate repeatable runout of the disk based on the measured timing, and to compensate for repeatable runout of the disk responsive to the estimated repeatable runout while positioning the transducer relative to a selected track.
