Bandwidth disc drive actuator

摘要

A disc drive with improved servo-mechanical frequency response includes a rotary actuator assembly incorporating stiffening members disposed along the sides of its actuator arms. In one embodiment the stiffening members comprises edge rails. The edge rails may rise from only the upper surface of the actuator arm or from both the upper and lower surfaces. In one embodiment the stiffening members comprise wings which project upward from the sides of the actuator arm.
