Abstract

A support arm is adapted for high-speed positioning of a transducer such as a read/write head in a magnetic disk drive. The support arm is essentially composed of a ceramic material having a high specific stiffness. The support arm is shaped to form structures integral of the support arm for mating with fasteners for connecting a transducer assembly to one end of the support arm and for connecting the support arm to a positioning actuator.
