Abstract
A disk drive is disclosed comprising a disk having a plurality of tracks, a head, and a voice coil motor (VCM) and a microactuator for actuating the head over the disk in response to a feed-forward compensation value. A sinusoidal disturbance is applied to the microactuator, and the resulting feed-forward compensation value is processed to characterize the microactuator.
