Disk drive including an airflow diverter element radially between spindle motor axis of rotation and cavity in shroud surface

摘要

A disk drive including a disk drive base and a cover attached to the disk drive base. The disk drive further includes a rotatable disk including a disk surface extending to an outer periphery. The disk drive further includes a spindle motor including an axis of rotation. The spindle motor is rotatably coupled to the disk drive base for rotating the disk about the axis of rotation. The disk drive further includes a shroud surface concentrically formed about and adjacent the outer periphery. The disk drive further includes a cavity formed in the shroud surface. The cavity extends to a cavity opening adjacent the outer periphery. The disk drive further includes an airflow diverter element extending from the cover towards the disk surface radially between the cavity opening and the axis of rotation for diverting disk rotation induced airflow adjacent the disk surface.
