Abstract
A venturi or other air deflecting means is provided on the inside of the casing of a disc drive. The venturi or air deflecting means is arranged so that air, which is caused to move by the rotating disc, passes it and creates the lowest pressure inside the disc casing. This low pressure area is communicated to atmospheric pressure.
