Abstract

A contaminant reduction system is shown for a disk drive assembly having a closed interior and slider disk components located therein which would be adversely affected by condensed volatiles generated within the assembly. A Peltier element is located within the closed interior of the disk drive assembly so as to condense volatiles present within the interior at a desired condensation point within the closed interior. A getter material, such as a microporous sintered alumina, is located within the closed interior of the disk drive assembly at the condensation point for permanently trapping and maintaining condensed volatiles which are condensed by the Peltier element.
