Abstract: A gas-charging head for charging a device with gas includes a body and at least one valve mounted on the body. The body includes a plurality of channels in communication with an interior space of the device operable to permit a flow of gas therethrough. At least one valve mounted on the body is in communication with a channel of the plurality of channels. The body and a portion of a channel are operable as a valve manifold for the valve. In another embodiment, a system for charging the device with gas that includes a proportional-integral-differential (PID) controller is provided. In yet another embodiment, a method of charging the device with a gas is also provided. The device may be a hard-disk drive, and the gas may be helium without limitation thereto.

Abstract: A hard drive particle cleaning system includes an air source, an ionizer module coupled to the air source via upstream tubing, a mechanical shock system configured to secure a hard drive and apply a mechanical shock to the hard drive to dislodge particles inside the hard drive, and an exhaust system. The ionizer module includes a shell and an inlet nozzle arranged in a first end of the shell and coupled to the upstream tubing for supplying a stream of air from the air source into the shell.

Abstract: A chassis for receiving a plurality of disk drives includes a plurality of disk drive receiving stations. Each station is configured to carry out testing and/or servo writing operations on a received disk drive. Each station includes a base, a nest assembly and a plurality of elastomeric mounts that elastically couple the nest assembly to the base to enable movement of the nest assembly relative to the base. The nest assembly includes a nest configured to receive and mate with the disk drive and a printed circuit board. Each station includes a separate vibration isolating mass that is coupled to the nest. The vibration isolating mass at least partially isolates vibrations originating within the nest from being transmitted through the elastomeric mounts to other nests in the chassis and at least partially isolates vibrations originating outside the nest from being transmitted through the elastomeric mounts to the nest assembly.
