Abstract
A disk drive that includes a disk drive base, a spindle motor hub, a disk, and a rotary actuator including a distal end and is formed to pivot for translating the distal end adjacent the disk to a parked position. The disk drive includes a disk plate that includes a plate body disposed substantially about and parallel with the disk for modifying air flow adjacent the disk during operation of the disk drive. In an embodiment the disk plate includes a head limiter portion extending from the plate body. The head limiter portion is vertically aligned with the distal end with the distal end in the parked position. In other embodiment the disk plate includes an arm limiter portion vertically aligned with the actuator arm structure with the actuator arm structure in the parked position.
