摘要： An apparatus for detachably mounting a head gimbal assembly to an actuator coil assembly is described. The apparatus includes a lever pivotally connected to an upper surface of an arm of the actuator coil assembly and operable to pivot between a release position and a mount position. A capture pin extends from the lever into a mounting hole of the arm. The capture pin is substantially perpendicular to the lever and is collectively pivotable with the lever between the release position and the mount position. A spring is arranged to exert a force on the lever in a direction from the release position to the mount position. The capture pin is configured to engage the head gimbal assembly positioned on a lower mounting surface of the arm opposite the upper surface of the arm via the mounting hole and to press the head gimbal assembly into the arm when in the mount position.

The vibration damping system is fixed adjacent the outer surface of the printed circuit board and includes an external planar member of compressible foam composition and a substantially-planar rigid mass damper of like shape and extent and arranged so that the external planar member contacts both the outer surface of the printed circuit board and the upper major surface of the mass damper. The major surfaces of the mass damper include upwardly-convex bosses for receiving fastening screws to maintain a predetermined separation distance between the printed circuit board and the mass damper that is somewhat less than the unconstrained thickness of the external planar member of compressible foam composition.
