Abstract
An improved cooling and filtration system for a disk file is provided in which a closed loop path is established in the disk enclosure extending from the area of the disk hub through holes in disk spacers radially outward across the disk surface, down the vertical walls of the enclosure and back to the impellar of the disk hub through one of two parallel branch segments of the closed loop. One of the parallel branch segments is through a high impedance, low volume filter branch which contains a filter to remove debris. The other branch segment is a low impedance, high volume branch which includes the hot side of a heat exchanger which is an integral part of the disk file baseplate on which the disk shaft and positioning system components are mounted. A separate open loop path outside of the disk enclosure extends from the impellar surface of the driving pulley attached to the disk spindle through the cold side of the heat exchanger.
