Abstract
A hard disk drive enclosure base includes a groove extending from an internal sidewall surface into the sidewall and a gasket seal embedded in the groove. In the context of progressively larger recording disk diameters, corresponding expanding disk shrouds, and corresponding narrower baseplate sidewalls, such a baseplate is configured to enable a first cover to physically engage with a portion of the embedded gasket seal that extends inward away from the sidewall surface, thereby providing a suitable drive sealing mechanism.
Claims14
A hard disk drive (HDD) comprising:
- a disk medium rotatably mounted on a spindle;
- a head slider housing a read-write transducer configured to read from and to write to the disk medium;
- an actuator configured for moving the head slider to access portions of the disk medium;
- and
- an enclosure base comprising:
- a groove extending from an internal surface of a sidewall into the sidewall, and
- a gasket seal embedded and encompassed at least 180 continuous degrees within the groove;
- wherein the groove and the embedded gasket seal are discretely positioned at each of a 0° position, a 90° position, and a 180° position of the base.
An enclosure base for a hard disk drive (HDD), the base comprising:
- a groove extending from an internal surface of a sidewall into the sidewall;
- and
- a gasket seal embedded and encompassed at least 180 continuous degrees within the groove;
- wherein the groove and the embedded gasket seal are discretely positioned at each of a 0° position, a 90° position, and a 180° position of the base.
A method of manufacturing a hard disk drive enclosure base, the method comprising:
- forming a groove extending from an internal surface of a sidewall of the base into the sidewall at each of a discrete 0° position, a discrete 90° position, and a discrete 180° position of the base;
- and
- embedding, and encompassing at least 180 continuous degrees, a gasket seal into the groove at each of the discrete 0° position, the discrete 90° position, and the discrete 180° position of the base.
