    Abstract: Various aspects of the present disclosure are directed toward a disc drive apparatus having an inner enclosure structure that resides within an outer disc drive enclosure. The inner enclosure structure includes an environment-adsorption material, an inner volume of gas, and an aperture-defining membrane. The environment-adsorption material combines a first-type of molecules with a second-type of molecules that are present in the outer disc drive enclosure. Additionally, the aperture-defining membrane facilitates diffusion of the second-type of molecules into the inner enclosure structure and into contact with the environment-adsorption material to adsorb the second-type of molecules into the first-type of molecules, which reduces the volumetric pressure in the outer disc drive enclosure.

    Abstract: The present invention relates to methods to join at least first and second metallic components in which a pre-treatment is applied to one or more region(s) of at least one of the components to be welded together before welding takes place. The pre-treatment involves contacting at least a region of the first metallic component with a rotating and translating tool such that the rotating and translating contact locally heats, softens, and mixes successive portions of at least the region of the first metallic component. The first and second metallic components are placed together such that a joint is provided between at least the pre-treated region of the first metallic component and the second metallic component. At least the pre-treated region of the first metallic component is welded to the second metallic component along at least a portion of the joint.
