ABSTRACT:
A hard disk drive head actuator includes a plurality of arms for holding the heads over the disks. Each arm is formed with one or more cutouts, to reduce the rotational inertia of the actuator. To prevent increased viscous dissipation, or windage losses, that would otherwise be caused by the cutouts, the cutouts are filled with lightweight plastic inserts. Advantageously, filling the cutouts improves structural damping of an arm and enhances the dynamic response of an actuator assembly that incorporates one or more such arms.
