ABSTRACT:
An apparatus positions a transducer, carried by a slider, over a track on a magnetic disk. An arm has a first end for attachment to an actuator for rotating the arm and a second end for attachment to the slider. The arm also has an arm portion extending between the first and second ends. A shape memory alloy is coupled to the arm portion. Thermal energy is selectively applied to the shape memory alloy to cause corresponding deformation of the shape memory alloy causing the arm portion to deflect and move the second end along an arcuate path in a plane substantially transverse to the track.
