Abstract

A combined controlled rate adsorbent and disc drive stabilizing unit in the shape of a computer disc including an adsorbent of planar shape, a casing of porous material having a predetermined water vapor transmission rate encasing the adsorbent for prolonging the water vapor adsorption time of the adsorbent, and a self-sustaining jacket on the casing of a shape for installation into a computer disc drive during transit.
