A valve apparatus for a storage device includes a tab configured to couple to an enclosure and a flap coupled to the tab by a flexure. The flap is configured to regulate airflow through a breather hole of the enclosure. The flap includes an opening configured to reduce airflow into the enclosure when the flap is in a closed position.

A base plate includes a support part, a bottom plate part, and a wall part. The wall part includes a first wall part and a second wall part above the first wall part. The first wall part includes a first wall surface and a support surface spreading from an upper end of the first wall surface to a radially outer side. The second wall part includes a second wall surface and a recess recessed to the radially outer side from the second wall surface. The recess is defined by a space enclosed by a recess wall surface located on the radially outer side of the second wall surface and extending upward from the support surface, a recess top surface connecting from an upper end of the recess wall surface to the second wall surface, and a recess support surface facing the recess top surface in an axial direction.

The present disclosure relates to a data storage device housing component (and related data storage devices) that include a polymeric element attached to a surface thereof. The polymeric element includes a polymeric matrix and a plurality of nanofiller elements dispersed within the polymeric matrix to increase the thermal conductivity of the polymeric element as compared to a polymeric element that does not include the plurality of nanofiller elements. Also disclosed are related methods.

An apparatus includes a drive base. A drive cover overlies the drive base. A fastener secures the drive cover to the drive base. The fastener extends through the drive cover and into the drive base. A gasket is between the drive base and the drive cover. The gasket is compressed by the drive base and the drive cover. A spring feature is formed in the drive cover. The spring feature exerts a first force on the fastener and a second force on the base. The first force is opposite the second force.

According to one embodiment, a disk device includes a rotatable recording medium, a head, and a housing which includes a first enclosed space accommodating the recording medium and the head, and a second enclosed space defined between the first enclosed space and outside air. Low-density gas is sealed in each of the first enclosed space and the second enclosed space, and a pressure of the first enclosed space is different from that of the second enclosed space.

A base member includes a recessed portion extending in radial directions and recessed upward from a lower surface of the base member and a hole extending through the recessed portion in the vertical direction. The recessed portion includes a recessed portion loop-shaped surface defining a loop-shaped surface in the radial direction. A connector is located on a lower side of the recessed portion to cover the hole portion. An adhesive is located between the connector and the recessed portion. A minimum value of a gap distance in the radial direction between an outer end of the connector and an inner end of the recessed portion in which the outer end of the connector and the inner end of the recessed portion are opposed to each other with the adhesive therebetween is greater than a minimum value of a gap in the vertical direction distance between an upper surface of the connector and the recessed portion loop-shaped surface, in which the upper surface of the connector and the recessed portion loop-shaped surface are opposed to each other with the adhesive therebetween. The adhesive includes an inorganic filler.

A disk apparatus includes a base including a bottom wall and a sidewall disposed along a peripheral portion of the bottom wall, a cover including a ceiling plate and a side plate disposed along a periphery of the ceiling plate, the ceiling plate being fixed to the sidewall and the side plate facing an outer surface of the sidewall, and a rotatable recording medium disposed between the cover and the bottom wall. The sidewall of the base includes a first portion adjacent to the recording medium and a protruding portion that protrudes from the first portion outward and away from the recording medium, and at least a portion of a sidewall of the protruding portion faces an opening formed in the side plate.

Provided is a base unit for use in a disk drive apparatus including a motor arranged to be capable of rotating about a central axis extending in a vertical direction. The base unit includes a base member arranged to extend radially to support the motor, and including a predetermined adhesion region and an outside region outside of the adhesion region; and a connector electrically connected to a wire arranged on the base member. The connector is adhered to the base member through an adhesive at the adhesion region of the base member. A wettability of the adhesive on the adhesion region is higher than a wettability of the adhesive on the outside region of the base member.

An apparatus includes a drive base. A drive cover overlies the drive base. A fastener secures the drive cover to the drive base. The fastener extends through the drive cover and into the drive base. A gasket is between the drive base and the drive cover. The gasket is compressed by the drive base and the drive cover. A spring feature is formed in the drive cover. The spring feature exerts a first force on the fastener and a second force on the base. The first force is opposite the second force.

A data storage device involves a plurality of sidewalls of a bent sheet metal cover, either pre-formed or shaped-in-place, overlapping with and hermetically sealed with a corresponding plurality of sidewalls of an enclosure base, using an applied epoxy adhesive. Base protrusions and/or cover dimples may be used to set a suitable gap between the parts. A robust hermetic seal provides for filling the data storage device with a lighter-than-air gas.
