Abstract
A data storage device involves a plurality of continuous sidewalls and corner portions of a tub cover overlapping with and hermetically sealed with a corresponding plurality of sidewalls and corners of an enclosure base using an epoxy adhesive. Base protrusions and/or cover dimples may be used to set a suitable gap between the parts. A robust hermetic seal provides for filling the HDD with a lighter-than-air gas. A tub cover may include corners having a tapered radius that decreases from the top to the bottom edge, and a base may include corners having a constant-radius outer surface and sidewalls having a sloped upper surface, whereby an assembly interference fit between the base and the tub cover is formed by forcing outward each sidewall of the tub cover while forcing inward at least a portion of each corner of the tub cover.
