Disc drive cover heat sink

摘要

A data storage disc rotatably mounted on a spin or spindle motor fastened to a base plate. An actuator assembly is fastened or otherwise coupled to base plate adjacent to data storage disc. The actuator assembly positions a transducer or head over a data surface of the disc. A cover above the base plate encloses the disc, the spin motor, and the actuator assembly between the cover and the base plate. A pass-through connector is positioned above and coupled to the base plate for routing electrical leads from the transducer through a preamplifier mounted above the pass through the pass-through connector to a printed circuited board located below an underside of the base plate. The cover has a surface thermally coupled to the preamplifier to conduct heat from the preamplifier.
