Abstract:
A hard disk drive with a circuit that provides a control signal to a voice coil motor to move a head across a disk. The circuit includes a repeatable run-out estimator in a feed forward control loop to control the movement of the head. The repeatable run-out estimator compensates for a constant bias torque disturbance in the drive.
