Abstract: Described are enclosures that include a friction stir weld, including electronic device enclosures, and precursors thereof that contain a metal base that includes a recess and a metal cover that in an assembled condition form a joint at which a friction stir weld can be produced, as well as methods for producing a friction stir weld at a joint of such an assembly; the base includes at least one bow wave reduction feature.

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.

Abstract: A hard drive includes a base deck and process cover that define a cavity for housing data storage components. The hard drive further includes a final cover that is placed over the process cover and is coupled to the base deck. The final cover and process cover are directly coupled to each other.

Abstract: A hard drive includes a base deck with sidewalls to define a cavity. The hard drive further includes a weld lip that is positioned along and extends from the sidewalls. The weld lip includes a thermal choke that is configured to reduce heat transfer from the weld lip to the sidewalls.

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: A method and combination for mitigating turbulent air flow across an actuator of a data storage device. The combination includes a base deck having a retention cam surface adjacent a mounting pin, and an air diverter having a mounting aperture and a spring portion with a cam follower. The air diverter is confined adjacent the base deck in an operating position by executing the steps of the method to form the combination. The method includes the steps of; providing the base deck, disposing the air diverter onto the mounting pin, attaching a spindle motor with a disc to the base deck, securing an actuator supporting a read/write head to the base deck and affixing a top cover to the base deck, which places the air diverter under a compressive load between the top cover and the base deck thereby fixing the air diverter in the operating position.

Abstract: An actuator assembly has a generally flat sheet metal body with upper and lower surfaces and an actuator bore passing therebetween. The actuator bore is sized to receive the bearing cartridge assembly therethrough. A plurality of tabs project inward from an interior surface of the actuator bore, wherein the tabs extend only partially along a depth of the actuator bore between the upper and lower surfaces. The tabs contact the bearing cartridge assembly and secure it within the actuator bore.
