Patent ID: 8274754

Claim:
A hard disk drive, comprising: an enclosure having a coordinate system defining x, y and z-directions, a base generally extending in an x-y plane direction, a sidewall extending from the base generally in the z-direction, the sidewall substantially circumscribing the base, and a transverse wall generally extending in the x-y plane direction from the sidewall, the transverse wall defining a partial bypass slot between the transverse wall and the base for communicating airflow to a main bypass channel; a magnetic media disk rotationally mounted to the base and, in operation, generating an airflow through the partial bypass slot, the magnetic media disk having a perimeter edge and a radial center; an actuator movably mounted to the base and having a transducer for reading data from the magnetic media disk; a diverter assembly mounted to the base adjacent to the magnetic media disk, the diverter assembly having a spoiler that extends in the x-y plane direction beyond the perimeter edge of the magnetic media disk toward the radial center of the magnetic media disk; and the diverter assembly is located completely external relative to the partial bypass slot, such that airflow through the partial bypass slot goes around the diverter assembly without passing over an x-y surface of the diverter assembly, and an x-z surface of the diverter assembly forms a wall for the partial bypass slot.
