Abstract
In accordance with various embodiments, a data storage device comprises a sealed housing which encloses a data storage medium. The sealed housing comprises a substantially planar first housing plate with respective length, width and thickness dimensions and a circumferentially extending first peripheral edge, a substantially planar second housing plate with a circumferentially extending second peripheral edge, and a circumferentially extending first sealing member contactingly disposed between the respective first and second peripheral edges. A substantially planar third housing plate extends adjacent the first planar housing plate with respective length and width dimensions substantially corresponding to the length and width dimensions of the first housing plate, and a circumferentially extending third peripheral edge. A circumferentially extending second seal member is contactingly disposed between the second and third peripheral edges to form a hermetic seal for the low density gas.
