Abstract
A closure seal for a storage device, such as a disk storage device, to block the flow of air into and out of the storage device. The storage device includes a base to support and contain mechanisms for accessing a storage medium, a cover to cover the base, and a single sheet closure seal to seal a boundary between the base and the cover, and to seal apertures in the base and cover. To prevent the formation of bubbles in the closure seal, at least one of the closure seal, the cover, and the surface to which the closure seal is affixed include at least one ventilation hole to release air during the operation of affixing the closure seal.
Claims41
A disk storage device comprising:
- a base to support an actuator device to access a storage medium, the base having an opening with a flat top edge surface;
- a cover received within the opening of the base at the top edge surface of the base with a space therebetween and attached to the base through at least one perforation in the cover, the cover having an exterior surface with a raised substantially flat portion around the at least one perforation, said raised substantially flat portion being co-planar with the top edge surface of the base,
- wherein the cover further includes a recessed, substantially flat portion;
- a damping plate member mounted in the recessed, substantially flat portion of the cover and including at least one hole to accommodate the raised substantially flat portion,
- a sheet seal affixed to the raised substantially flat portion of the cover, the damping plate, and the top edge surface of the base to seal the at least one perforation and the space between the top edge surface of the base and the cover.

A storage device, comprising:
- a base to support an actuator device to access a storage medium, the base including an opening with a flat top edge surface;
- a cover received within the opening of the base at the top edge surface of the base with a space therebetween and attached to the base through at least two holes formed in the cover and the base, respectively,
- wherein one of the holes is formed in a first raised substantially flat peripheral portion of the cover, and another of the holes is formed in a second raised substantially flat interior portion of the cover,
- wherein said top edge surface of the base, the first raised substantially flat peripheral portion and the second raised, substantially flat portion are co-planar, and
- a sheet seal affixed to the cover at the first and second raised substantially flat portions and the top edge surface of the base to seal the two holes and the space between the cover and the base.
2 more elements
A device, comprising:
- a base having a top, a bottom, sides and an opening to receive a disk drive;
- a cover having an exterior surface and including a plurality of first holes,
- wherein the base has a flat top edge around the opening, the cover has a flat peripheral edge, the base top edge receives therewithin the cover peripheral edge, and the top flat edge of the base and the flat peripheral edge of the cover are co-planar;
- wherein the cover is attached to the base through the plurality of first holes formed in the cover,
- a damping plate received within the cover and having at least one ventilation hole to allow air to pass through the damping plate;
- and
- a sheet seal that extends beyond the edges and seals, in an airtight manner, the plurality of first holes and the at least one ventilation hole and the edges.
4 more elements
A device, comprising:
- a base having a top, a bottom, sides and an opening to receive a disk drive;
- a cover having an exterior surface, a first raised peripheral substantially flat portion with at least one screw hole formed therein, a second recessed substantially flat portion that is formed interiorly of the first portion, and a third raised substantially flat portion that is formed interiorly of the second portion with at least one screw hole;
- a damping plate member mounted in the second portion of the cover and including at least one opening to accommodate the third portion therein,
- wherein the cover is received by the opening of the base and screws extend through the screw holes formed therein for attaching the cover to the base and the cover to the disk drive, respectively, and
- wherein the base has a top edge around the opening of the base, the cover has a peripheral edge, the base top edge receives therewithin the cover peripheral edge;
- and
- a sheet seal affixed to the exterior surface of the cover to extend over and seal in an airtight manner the edges and the screw holes,
- wherein the base includes at least one hole, and a second sheet seal extends over the at least one hole of the base and seals, in an airtight manner, the at least one hole in the base.
