Abstract
A sealed head disk assembly has a base casting for providing attachment points for the major components of the head disk assembly. The base casting has a semi-hermetic seal encompassing an outer perimeter of the base casting and allows the semi-hermetic seal to be juxtaposed to at least one complementary surface on the cover. The cover for enclosing the major components of the head disk assembly has a hermetic seal outside a perimeter of the complementary surface for the semi-hermetic seal thus allowing the hermetic seal to be juxtaposed to at least one complementary surface on the base casting.
