Abstract
A novel self-securing sealing gasket for a disk drive assembly housing ensures predictable securement of the sealing gasket to a mounting surface. Elastomeric material is preferably molded to a rigid frame. The elastomeric material defines the sealing member of the gasket, while the frame provides structural rigidity and concomitant ease of handling during assembly and disassembly of the disk drive assembly housing. A plurality of recesses are provided along the periphery of the frame for mechanically coupling with the sealing member. The compliant sealing member includes a first sealing surface having a convex profile. A plurality of vacuum cavities are integrally incorporated along a second sealing surface of the sealing member for providing vacuum coupling between the second sealing surface and the mounting surface of the base of a disk drive assembly housing. Predictable securement of the sealing gasket to the housing base during disassembly of the disk drive assembly housing is provided by the vacuum coupling between the second sealing surface and the base mounting surface in conjunction with a repellant force generated by the convex shape of the first sealing surface which is…
