Disc Drive Apparatus with Hermetically Sealed Cavity

摘要

Certain exemplary aspects of the present disclosure are directed towards a disc drive apparatus. A base deck and a cover are joined to one another by a friction-stir weld along a lip of the cover that extends along a periphery of the cover and over a surface of the base deck. The base deck and cover enclose a cavity, which is hermetically sealed by the weld.

主权项

1. A disc drive apparatus comprising:
a base deck including a cavity defined by sidewalls having inner surfaces; a cover that encloses the cavity, the cover including a planar inner surface that adjoins the inner surfaces of the sidewalls to enclose the cavity, and including a lip that extends along a periphery of the cover and that bends over an outer surface of the sidewalls of the base deck; and a friction-stir weld that joins a lower portion of the lip to the base deck along the outer surface of the sidewalls, the friction-stir weld including a portion of first material from the lip blended with a portion of second material from the base deck, the friction-stir weld being configured and arranged with the cover and base deck to hermetically seal the cavity.
