Abstract: A hard disk drive (HDD) includes an enclosure base, a first cover coupled to the base, and two separate gasket seals composed of different materials and configured to seal the interface between the first cover and the base. One gasket seal is composed of a material having a low permeability to helium or another lighter-than-air gas contained within the HDD, and the other gasket seal is composed of material having a low water vapor or moisture transmission. By using two separate independent gaskets which have different attributes, the lighter-than-air gas concentration is kept high and humidity is kept low during manufacturing testing, prior to affixing a hermetic second cover over the first cover, and degradation of HDD performance due to change of flying height is ultimately avoided.
