Disc drive gas supply system

Abstract

A disc drive gas supply system for supplying a gas other than air to an enclosed environment containing a disc includes a source of gas other than air, which can be connected to the enclosed environment. A pressure sensor produces a pressure signal, such as an electrical, pneumatic, or mechanical signal, that is representative of the pressure within the enclosed environment. A control module receives the pressure signal and connects the source of gas other than air to the enclosed environment if the pressure within the enclosed environment is within a predetermined pressure range. When the pressure within the enclosed environment is above the predetermined pressure range, the control module disconnects the source of gas other than air from the enclosed environment. A disc drive shipping and storage package includes a disc drive defining an internal enclosed environment containing a gas other than air. The package also includes a sealed storage container containing the disc drive and defining an external enclosed environment that also contains the gas other than air.
