Top cover having a turbo tunnel for an air vane latch apparatus in a disc drive

Abstract

An apparatus for increasing the operative force on an air vane latch apparatus in a disc drive has a channel formed in the inside surface of the side wall of the head disc assembly cover immediately upstream of the air filter portion of the air vane latch apparatus for redirecting disc generated air flow against an air vane latch air filter and filter support bracket thus increasing the wind force on the air vane latch during disc drive operation to reduce the disc speed at which the latch apparatus moves from a latched position to an unlatched position.
