An apparatus includes a test chamber and a pressure-application structure. The pressure-application structure is configured to apply a force on a device under test within the test chamber in response to a vacuum being drawn in the test chamber. The force has a magnitude that is proportional to a difference between an external pressure outside the test chamber and an internal pressure within the test chamber.

Retaining internal pressure in a data storage device in a vacuum

A process for assembling data storage components in which a cylindrically shaped first structure of a data storage device is inserted into an aperture of a second structure, the first structure having a circumferentially extending outer surface and the aperture of the second structure having an aperture sidewall. An annular gap is formed between the outer surface of the first structure and the inner sidewall of the aperture of the second structure, and a plurality of discrete dots of adhesive are placed to span the annular gap following which the adhesive is cured by exposing the adhesive to ultraviolet radiation to attaches the first and second structures into a sub-assembly.

An apparatus for use in attaching a head gimbal assembly (HGA) onto an actuator arm of an actuator assembly during an HGA installation process. The apparatus includes, a central body portion with a base support surface; and a pair of support arms extending from the central body portion forming a channel sized to accommodate expansion of an attachment aperture of an actuator arm during the installation process. Each support arm includes, a first and second support surface offset from and parallel to the base support surface. A first support arm thickness is formed between the first support surface and the base support surface, while a second support arm thickness is formed between the second support surface and the base support having a thickness less than the first support arm thickness. Each support arm thickness supports a corresponding HGA adjacent actuator arm during the installation process.
