Abstract
A novel disk drive includes an enclosure and a disk rotatably mounted to and within the enclosure. The disk drive enclosure has a fill port opening with an internally threaded section and an internal annular seating surface. A fill port valve is disposed within the fill port opening. The fill port valve includes an externally threaded section that is engaged with the internally threaded section of the fill port opening, an external annular seating surface in contact with and forming a continuous annular seal with the internal annular seating surface of the fill port opening, and a gas flow channel spanning the externally threaded section of the fill port valve. The disk drive may be helium-filled, and may also include a metal foil seal that is externally adhered to the disk drive enclosure and covers the fill port opening and the fill port valve.
