Abstract
An airflow damper is affixed to a top interior wall of a hard disk assembly, so that a specified gap distance between the airflow damper and an upper disk within the hard disk assembly is realized. The gap distance is determined as a function of velocity of the driven disks. The airflow damper is designed to have a thickness so that the determined gap distance is realized for the given velocity. The airflow damper eliminates secondary airflow within the hard disk assembly, to prevent formation of a large vortex above the upper disk and to thus reduce airborne noise.
