Abstract
Described herein is a hard disk drive that includes a base and a cover. The base includes a closed end, sidewalls, an open end, and one or more corner portions. The sidewalls extend from the closed end, and the open end is defined by the sidewalls. The closed end, sidewalls, and open end define an interior cavity of the hard disk drive. Each corner portion is proximate a respective intersection of the sidewalls and positioned exteriorly of the interior cavity. The cover is welded to the sidewalls over the open end by a weld bead such that the weld bead is positioned between the interior cavity and the corner portions. The weld bead hermetically seals the cover to the base. Furthermore, at least one of the corner portions is at least substantially flush with the cover.
