Integrated cover and gasket assembly

Abstract

A disc drive includes a base and a disc rotatably attached to the base. The disc drive also includes an actuator assembly rotatably attached to said base and a device for moving the actuator assembly. A cover is attached to the base. The combination of the cover and base form a disc enclosure for enclosing the disc the actuator assembly and the device for moving the actuator assembly. The cover includes a first layer having a rubber gasket attached thereto, a second layer, and a third layer of damping material positioned between the first layer and second layer. The gasket may be attached to the cover. The gasket may also be formed integral with the cover. The cover reduces relative motion between the actuator assembly and the base while under any type of servo control that requires corrections to be implemented with the voice coil motor. The disc drive may also include a base having first and second layers of stainless steel, a rubber gasket attached to the first layer, and a layer of damping material between the first and second layers.
