Abstract
An actuator comprises a slotted stator which is mounted in a stator frame. The stator is connected to the frame by an attachment which allows the stator to move rotationally, axially and laterally relative to the frame without distorting the dimensions of the stator. The stator has an air bearing outer surface which receives a slider. A head arm assembly is attached to the slider such that the head arm assembly may be completely positioned within the stator slot when the slider is fully retracted.
