ABSTRACT:
An expandable gasket for a head disk assembly, wherein the gasket is initially formed having a geometry that maximizes the number of gaskets realized per sheet of material used. The gasket includes a series of spaced-apart thinned pivot regions and is expanded from an initial relatively closed, material-saving geometry to a second, open geometry dimensioned to be disposed between a top cover and a base of a disk drive. In addition, the transformation from first to second geometries is accomplished without stretching, distorting, buckling or tearing the elongate pivot regions.
