Abstract
An actuator arm for a rotary actuator assembly of a disc drive comprises a substantially planar sheet of pliable material defining a longitudinal actuator arm having longitudinal edges, a distal end supporting the transducer, a proximal end supporting an actuator coil. Strut means integral with the sheet extends substantially normal to the plane of the sheet along at least a portion of at least one longitudinal edge and the proximal end of the arm to provide rigidity to at least a portion of the arm. In one embodiment, an integral strut portion defines a support for the actuator coil. In another embodiment, integral strut portions extend along opposite longitudinal edges to a location proximal the distal end to define a rigid portion between the strut portions and a flexible suspension region distal to the rigid portion.
