Abstract
A stationary plate functions as a vibration damper and has an integrated air filtration guide. In one embodiment the stationary plate is disposed between two adjacent disks, and the guide comprises one or more grooves through which rotation-induced air may flow. In another embodiment, a plurality of stationary plates may be disposed between a plurality of disks, wherein each of the plurality of stationary plates has a grooved side through which the rotation-induced air may flow. In still another embodiment, the orientation of the grooves in the stationary plate is such that the rotationally-induced airflow impinges the disk drive's voice coil motor.
