摘要： An archival data storage system library includes magnetic-recording disk media, a storage enclosure in which the media are housed, data storage devices (DSDs) configured to write to and read from the media, an automated disk handling mechanism configured to transfer at least some of the media between the storage enclosure and the DSD, and a hermetic enclosure containing the foregoing components. The storage system may further include a gas circulation system for filtering contaminants from the hermetic enclosure. Such a storage system may be implemented as a rack-mountable unit, or as an entire cleanroom facility, as well as in intermediate form factors between those. In the context of a cleanroom storage system, the system may further include an automated disk handling shuttle to receive the media from the disk handling mechanism and an automated disk loading mechanism for accessing the media from the shuttle for installing into the DSD.

摘要： A disc device includes a first traverse chassis holding a first optical pickup unit which performs recording/reproduction of information on a first surface of a disc, a second traverse chassis holding a second optical pickup unit which performs recording/reproduction of information on a second surface of the disc, and first and second biasing members which bias the first and second traverse chassis, respectively, in directions of coming closer to each other. The first and second traverse chassis are coupled to each other so as to turn around a turning axis at a rear side of a housing and extending in a width direction of the housing. At least one of the first and the second biasing members is attached while being inclined with respect to each of a conveying direction of the disc, and a thickness and the width directions of the housing.

摘要： 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.
