ADHESIVE COVER SEAL FOR HERMETICALLY-SEALED DATA STORAGE DEVICE

摘要

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.

主权项

1. A data storage device comprising:
an enclosure base comprising a plurality of sidewalls and corner portions; a tub cover comprising continuous sidewalls extending from a top portion and including corner portions, wherein each said sidewall and said corner portion of said tub cover overlaps at least in part with a corresponding said sidewall and a corresponding said corner portion of said base; and a hermetic seal among said base and said tub cover, comprising:
an epoxy adhesive at:
an interface of each said sidewall of said tub cover and each said corresponding sidewall of said base, andan interface of each said corner portion of said tub cover and each said corresponding corner portion of said base.
