According to one embodiment, a disk device includes a recording medium of a disk form, a magnetic head, a housing, and a first protective member made of a resin. The recording medium includes a recording layer. The magnetic head is configured to read/write information from/to the recording medium. The housing includes a base provided with an inner chamber in which the recording medium and the magnetic head are accommodated, a cover that covers the inner chamber, and a welded part at which the base and the cover are welded to each other. The first protective member is located outside the housing, to cover at least part of the welded part.

According to one embodiment, a disk device includes a housing with a bottom wall, magnetic disks supported on a hub of a motor, a printed circuit board provided on an outer surface of the bottom wall, and a wiring board attached on the outer surface of the bottom wall. The bottom wall includes a recess formed in the outer surface, a step located on border between the outer surface and the recess, and through holes opened to the recess. The wiring board includes one end portion disposed in the recess and connection pads on the one end portion, connected to lead wires of a coil. An adhesive is filled into the recess and the through holes, and covers the one end and a solder joint and seals the through holes.

A base member serves as a part of a housing of a hard disk drive device. The base member includes a base body being a cast product, a first machined surface obtained by machining a portion formed with a convex portion of the base body, and a coating film covering a surface of the base body. The base body includes a coated surface obtained by covering the first machined surface with the coating film, and a second machined portion obtained by machining a part of the base body other than the first machined surface.

According to one embodiment, a disk device includes a housing having a first transmission hole, a magnetic disk, a head, a first sealing material having an inner surface and an outer surface and closing the first transmission hole, and a first wireless power feeding device having a first power feeding antenna. The first power feeding antenna is located mere inward of the housing than the outer surface of the first sealing material, and receives power transmitted through the first sealing material by wireless power feeding.

An adhesive is filled into the recess and the through holes, and covers the one end and a solder joint and seals the through holes.

Described are enclosures for electronic devices; the enclosures include a cover, a base, and a snap-fit engagement between the cover and the base; also described are methods of preparing the devices.

An electronic device includes persistent storage enclosed within a housing. The housing is configured to protect the persistent storage during shipment of the electronic device by a common carrier. The electronic device may include at least one security door, which when in an open-state, may provide access to at least one of a data port, an aperture, a portion of a display, and/or the persistent storage. When the security door is in a closed-state and possibly locked, the persistent storage may be protected from environmental factors, such as dirt, weather, and tampering. In some embodiments, the aperture may enable airflow though the housing and may be fitted with a filter to remove debris from air that circulates into the housing.

A spindle motor includes a rotating part, a base member, a connector, and a connector accommodating recess in the base member. The connector accommodating recess includes a bottom surface and an annular wall surface extending from the bottom surface to the outer surface. A through-hole is formed in the bottom surface. The bottom surface includes a first annular surface extending toward the annular wall surface from a peripheral edge of the through-hole, and a second annular surface extending around the first annular surface on an axial outer surface side of the base member relatively to the first annular surface. The connector contacts the second annular surface. A first gap between the connector and the first annular surface is filled with an adhesive. An interface of the adhesive extends i to protrude from an inner peripheral surface of the through-hole over an entire circumference of the through-hole.

According to one embodiment, a disk device includes a disk-shaped recording medium, a head which processes data on the recording medium, and a housing accommodating the recording medium and the head. The housing includes a base with a side wall, and a cover having a welded portion welded to the side wall by laser welding. The welded portion includes a first welded portion welded to a first region of the side wall and having weld beads with a first shape, and a second welded portion welded to a second region of the side wall and having welded beads with a second shape different from the first shape.
