Abstract

A sealed disk media enclosure is provided. The sealed disk media enclosure in one example includes a media enclosure structure formed of a porous material and including a disk media chamber and a chamber aperture on one side of the media enclosure structure, one or more disk media located in the disk media chamber, a Diamond-Like Carbon (DLC) coating on at least a portion of the media enclosure structure, with the DLC coating preventing passage of gas molecules through the media enclosure structure, and a cover affixed to the media enclosure structure and substantially sealing the chamber aperture, wherein a predetermined gas or gas mixture is sealed within the disk media chamber.

Description

technical field [0001] Aspects of the present disclosure relate to the field of data storage systems, and in particular to a sealed disk media enclosure. Background technique [0002] Hard disk drives (HDDs) include electronic storage devices that store digital information. HDD includes one or more magnetic disks. These disks typically include optical or magnetic media capable of storing large amounts of digital information. The disks are spun to read or write digital information on the disks. [0003] One problem that can occur in HDD devices is oxidation of the disk surface. The oxide layer can interfere with reading from or writing to the disk. The oxide does not have to be significantly thick to interfere with read and write operations of the disk. Therefore, manufacturers of HDD devices take measures to remove oxygen and / or moisture inside the HDD device and prevent oxygen and moisture from penetrating into the HDD device. [0004] The old way to stop oxidation is...
