Abstract: 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.

Abstract: A disc drive includes an actuator assembly mounted on a base. The actuator assembly is able to move a transducer head over a data surface of a disc. The disc drive also includes a voice coil motor that is able to rotate the actuator assembly. The voice coil motor includes a bottom pole adjacent the base, an opposing top pole adjacent the cover and a coil mounted on the actuator assembly between the top and bottom poles. A flexible cable is coupled to the head and has first and second ends and a middle section extending between the first and second ends, wherein the first end is secured to the actuator assembly. The disc drive also includes a flex clamp fastened to the base and securing the second end of the flexible cable to the base. The flex clamp has a body and a clamp arm extending from the body. The clamp arm extends over the bottom pole of the voice coil motor and retains the bottom pole between the clamp arm and the base.
