Abstract
A combined shock mount frame and seal for a rigid or hard disk drive is constructed by attaching a compressible seal to the edge of a rectangular rigid plastic frame. The seal is provided with a circumferential angular groove on an interior portion having a depth slightly greater than half the thickness of the mounting base of the head and disk assembly of the drive. A circumferential angular ridge is formed on an exterior portion of the seal to conform to the mating edge of the covers of the drive enclosure. The frame is externally dimensioned to fit inside the covers of the drive enclosure. In use, a frame is placed inside a top and bottom cover of the drive enclosure. The mounting base is compressively held in the grooves of the seals of each of the two frames to provide shock resistance to the head and disk assembly and the ridge is compressively held between the mating edges of the covers to hermetically the drive enclosure.
