Patent ID: 8760797

Claim:
A disc drive apparatus comprising: an inner enclosure structure configured and arranged for residing within an outer disc drive enclosure, the inner enclosure structure containing therein an environment-adsorption material configured and arranged for combining a first-type of molecules contained within the environment-adsorption material with a second-type of molecules present in the outer disc drive enclosure, and an inner volume of gas surrounding the environment-adsorption material with a volumetric pressure less than a volumetric pressure contained in the outer disc drive enclosure; and an aperture-defining membrane configured and arranged for covering at least a portion of the inner enclosure structure and for facilitating a diffusion of the second-type of molecules into the inner enclosure structure and into contact with the environment-adsorption material, the environment-adsorption material containing the first-type of molecules for adsorbing the second-type of molecules into the first-type of molecules, therein reducing the volumetric pressure in the outer disc drive enclosure.
