Abstract:
A self servo-write process in performed on two or more recording surfaces simultaneously. In a dual-stage servo system, a first fine positioning servo system that includes a first microactuator independently controls the position of a first read/write head over a first recording surface of a hard disk drive, while a second fine positioning servo system that includes a second microactuator independently controls the position of a second read/write head over a second recording surface of the hard disk drive.

Claim (Index 6):
A disk drive comprising:\n a first magnetic head and a second magnetic head; a first microactuator provided at an end of an actuator arm, coupled to the first magnetic head, and configured for fine positioning of the first magnetic head; a second microactuator provided at the end of the actuator arm, coupled to the second magnetic head, and configured for fine positioning of the second magnetic head; a voice-coil motor configured for coarse positioning of at least the first magnetic head; and a first servo system configured to:\n position the first magnetic head over a first disk surface of a first disk with the voice-coil motor, the first microactuator, and a first servo controller that receives a first position signal from the first magnetic head and transmits a first correction signal based on the first position signal to the first microactuator; and \n while positioning the first magnetic head over the first disk surface, write servo information for a first track on the first disk surface with the first magnetic head; and \n a second servo system configured to:\n while the first servo system positions the first magnetic head over the first disk surface, position the second magnetic head over a second disk surface of a second disk with the second microactuator, and a second servo controller that receives a second position signal from the second magnetic head and transmits a second correction signal based on the second position signal to the second microactuator; and \n while positioning the second magnetic head over the second disk surface, write servo information for a second track on the second disk surface with the second magnetic head.
