ABSTRACT:
A head load/unload and airflow control apparatus for a disk stack is disclosed. Load/unload cams protrude into the OD of the disk stack for guiding the heads away from the corresponding disks during unloading and ramping the heads toward the corresponding disk during loading. Airflow vanes, each in the same plane and radially proximate to the outer edges of the corresponding disks are provided to limit airflow turbulence at the edge of the disks. Each airflow vane supports corresponding load/unload cams. A shroud supports the vanes and extends axially of the disk stack to limit airflow from the disks. The load/unload cams, airflow vanes and shroud may comprise a single element.
