The disk assembly filter system provides a means of taking air within a disk enclosure, filtering the air, and discharging it in the servohead area, thereby providing a cleaner operating environment for this critical file area. At the periphery of the disks, shroud 1 is open between the disks 2 and closed outside of the disk pack. This allows for gathering maximum energy in the chamber 4 upstream of the recirculating filter assembly 3. The air slung off the disk pack and gathered by shroud 1 is filtered and routed downstream into duct 6. Duct 6 is located below the disk pack in the servohead area. The clean filtered air passes through duct 6 and exits through nozzle 7 just upstream of the servohead. This technique keeps the servohead continually "bathed" in a stream of clean air.
