Abstract:
A hard disk drive that includes a voice coil motor and a micro-actuator. The micro-actuator is controlled by a servo that utilizes a micro-actuator controller and a corresponding micro-actuator transfer function. The servo enters a mode to self-determine at least one transfer function coefficient of the micro-actuator controller.
