Abstract
A disc spindle provides removal of particulates generated by internal parts of mechanisms, including the disc clamping mechanism, air bearing rotor, and other moving parts provides a port that is coupled to a vacuum system to remove particulate from the areas in which they are generated. In other aspects of the invention, vacuum evacuation of rotary and other bearings in a mechanical system employed in a clean room environment are prevented from contaminating the environment by removing particulate at the locations in which it is generated by friction, contact, or other means such as being introduced from the pressure channel in an air bearing feed.
