摘要： A disk drive is disclosed comprising a disk surface comprising a plurality of tracks, each track comprising a plurality of servo sectors. The disk drive further comprises a head coupled to a distal end of an actuator arm, and a voice coil motor (VCM) and a microactuator operable to actuate the head over the disk surface. The head is first servoed in response to the servo sectors, and after first servoing the head, a manufacturing procedure is executed by controlling the VCM and the microactuator to servo the head while accessing the disk surface. After executing the manufacturing procedure, the head is second servoed in response to the servo sectors, and the microactuator is evaluated in response to the first and second servoing.
