Abstract
A disc drive having a base plate and an information storage disc supported for rotation by a drive motor on the base plate. The disc drive further includes a rotary actuator assembly mounted on the base plate adjacent the information storage disc. The actuator assembly has an actuator arm carrying a transducer at a distal end thereof and a voice coil motor operably attached to the actuator arm for movement of the transducer over the disc. The voice coil motor has a vertically extending shroud flange positioned adjacent the outer peripheral edge of the disc, whereby the shroud flange directs air-flow along the peripheral edge of the disc during drive operation.
