ABSTRACT:
A separate elastic shroud to surround a disk pack is inserted into a disk drive housing after the disk pack and the actuator of the disk drive have been merged. This improvement simplifies manufacturing and assembly. The shroud may contain a filter which permits the passage of air from within the shrouded enclosure to outside the shrouded enclosure, and the filter is disposed in a region wherein a positive pressure exists within the disk pack enclosure relative to the pressure immediately outside the shroud. The shroud further may be provided with flanges or ribs which will engage the periphery of deflected disks of the disk pack to eliminate disk-to-disk contact, thereby reducing damage to the disk drive mechanisms and the disks proper. The shroud, filter design and placement, as well as the inlet and outlet shapes of the shroud each contribute therefore to reduce energy consumption and temperature rises within the disk drive.
