Abstract
A system and method are provided for controlling operation of an actuator for retracting a read/write head of a hard disk drive system. One aspect of the system and method relates to controlling the actuator in response to a retract request command by first decelerating the actuator for a time period and then braking of the actuator for another time period. Another aspect of the system and method relates to controlling operation of the actuator during retract based on a sensed back EMF relative to a target back EMF, which may be selected by a user.
