ABSTRACT:
A disk drive having an actuator arm for positioning a magnetic recording head over a magnetic surface is disclosed. The actuator arm has a supported end for connection to a rotatable shaft and a free end opposite the supported end for supporting a flex arm and a magnetic recording head/gimbal assembly. Between the supported end and free end is a tapered body including a first major surface extending from the proximal end to the distal end, a second major surface extending from the proximal end to the distal end, and first and second longitudinal edges. The body is thicker at the proximal end than at the distal end, and is thicker along its central longitudinal axis than at the first and second longitudinal edges.
