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.

Abstract: A housing has a base that includes a baseplate and a rail. The rail projects outwardly to an impact rim along a bottom edge of the rail. The rail includes a flexible web that couples the impact rim to the baseplate. A projecting contact surface on the impact rim is laterally offset from at least one bending axis through the flexible web. An impact to the contact surface is offset from the bending axis by a moment arm.

Abstract: An enclosure is provided defining an annular shroud adapted for receivingly engaging a rotatable data storage media. A method is provided for managing fluid flow created by a moving data storage medium, the method comprising circumscribing an annular shroud adjacent to an edge of the medium. A data storage device is provided comprising a rotatable data storage disc, and a fluid flow conditioner for minimizing excitation imparted to the disc by steps for managing fluid flow surrounding the disc.
