Abstract:
A method for reducing servo seek settling time in a disk drive apparatus, including an actuator for positioning a read/write transducer head at an initial location and a target location defined on a rotating disk, the method comprising the steps of:moving the read/write transducer head from the initial location toward the target location with the actuator; monitoring an absolute position value of the read/write transducer head prior to the read/write transducer head stabilizing at the target location, the absolute position value being defined by either a positive value or a negative value; selectively activating a gain enhancement control signal when the absolute position value changes between the values; and combining the gain enhancement control signal with a closed loop control signal to further move the read/write transducer head toward the target location, prior to the read/write head stabilizing on the target location.
