摘要： An apparatus includes a movable member, and first and second actuators coupled to the movable member at positions offset from a first axis that passes through a centroid of the movable member. A controller independently controls the first and second actuators to exert a first force on the movable member in a direction generally parallel to the first axis, thereby controlling both linear and rotational orientation of the movable member. The apparatus can further include third and fourth actuators coupled to the movable member at positions offset from a second axis that passes through the centroid of the movable member, and the controller can independently controlling third and fourth actuators.

摘要： A method and system determines the position of a transducer head based on permanent servo marks in which the width of the permanent servo marks is greater than the width of the data tracks they are used to identify. The method includes receiving readback signals in response to the permanent servo marks arranged as a number of null bursts and generating position error signals with respect to each null burst. Region based information is extracted based on the position error signals, and the region based information is used in conjunction with the position error signals to generate region-based displacement estimates with respect to each null burst. The region-based estimates are then combined to generate a final displacement estimate that describes the estimated distance between a transducer head and the centerline of a desired data track.
