Abstract
An apparatus for increasing the operative force on an air vane latch apparatus in a disc drive includes an air gate having an elongated rib extending parallel to the air vane immediately downstream of the air vane for reducing pressure behind the air vane during disc drive operation to reduce the disc speed at which the latch apparatus moves from a latched position to an unlatched position. The air gate is preferably a rib extending along an underside surface of the head disc assembly cover positioned parallel to the air vane and immediately downstream.
