ABSTRACT:
A disk drive includes a magnetic element having first and second magnets extending radially with respect to an axis of rotation of an actuator. The disk drive further includes a main coil. The main coil includes first and second radial segments. The first radial segment overlaps the first magnet throughout a full range of motion of the actuator. The second radial segment overlaps the second magnet throughout the full range of motion of the actuator. The disk drive further includes a secondary coil which is separately energized from the main coil. The secondary coil is configured to produce magnetic forces upon the actuator substantially parallel to the actuator longitudinal axis. The secondary coil includes a lateral segment disposed perpendicular to the actuator longitudinal axis and overlapping the first and second magnets throughout the full range of motion of the actuator.
