Abstract:
An airflow control device for a hard disk drive comprises an outer perimeter having a radius equal to or greater than an outer radius of a disk in the hard disk drive. The airflow control device has a thickness less than the spacing between adjacent disks in the hard disk drive. The airflow control device has a central opening with an inner perimeter greater than the outer circumference of a spacer ring of the hard disk drive. A notch in the outer perimeter is configured to accommodate the actuator assembly of the hard disk drive. A bypass slot transecting the perimeter has a bend with a radius nearly centered to the central opening.
