Abstract
An airflow control device in a disc drive to remove turbulence from air currents used to aerodynamically support a read/write head adjacent a rotatable disc. The direction of disc rotation is such that a given point on the disc reaches the head prior to reaching an arm used to support the head over a complete revolution of the disc. The airflow control device is placed upstream from the head and forms a channel within which the head moves across the disc. The airflow control device includes a diverter member upstream from the head and a screen member which extends over the head. During operation, air currents impinge upon the diverter member and most of these currents are diverted away from the head. A small portion of the air currents passes through a gap between the diverter member and the disc and flows on to the head to support the head.
