Unified disc drive top cover and voice coil motor pole |
摘要 |
A disc drive is disclosed that incorporates a voice coil motor pole into the drive cover. The disc drive has an actuator assembly mounted adjacent the storage disc that carries a trasducer at one end for transferring data to and from the disc, and a voice coil motor for rotating the actuator arm to position the transducer. The voice coil motor has a movable coil fastened to an opposite end of the actuator arm and a pair of stationary magnets positioned adjacent the voice coil in a side-by-side relation. A cover on the baseplate encloses the actuator assembly and the data storage disc and a portion of magnetically permeable material of the cover forms a top pole for the pair of magnets.
