<p>An air circulation control system for a magnetic recording disc drive employing a baffle pivotally mounted near the shroud which encircles the disc pack. A torsion spring holds the baffle in a retracted position against the shroud adjacent to the head access opening in the shroud for insertion and removal of disc packs. Rotation of the disc packs causes air flow across the baffle until the air flow pulls the baffle into the spaces between the discs of the disc pack. Thereafter the baffle causes an air pressure differential around the periphery of the disc pack which is used to pump cooling air through the disc drive.</p> |
