Abstract
Method and apparatus for protecting a data storage device from fluid-borne contaminants. The device includes a housing in which a rotatable disc is supported, the disc having a data recording surface and an outermost perimeter. A filter assembly includes a first filter adjacent to the data recording surface and a second filter disposed beyond the outermost perimeter of the disc. During disc rotation, fluidic currents are generated and impinge a leading edge guide surface of the first filter. A first portion of the currents passes into a gap between the first filter and the data recording surface. A second portion of the currents passes along the leading edge guide surface to the second filter. The first filter is preferably characterized as a chemical adsorbent filter which adsorbs vapor phase (gaseous) contaminants, and the second filter is preferably characterized as a pass-through recirculation filter which captures particulate contaminants.
