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 removable disk clamp assembly for mounting disk media on a motor-driven spindle of a magnetic read-write device includes a disk clamp and a mechanism for generating a predetermined force to press the disk media to a flange of the spindle such that the predetermined force can be repeatedly overcome by an applied counterforce to remove the disk clamp from engagement with a hub of the spindle. Such a mechanism may include a spring-loaded removable disk clamp assembly or a magnetic removable disk clamp assembly, and whereby a vacuum-driven chuck may be employed for disk and clamp handling purposes, all of which are suitable for implementation and use in a read-write device configured for use in an archival data storage system library such as in a cleanroom storage system.

A magnetic read-write device includes a disk spindle on which disk media are rotatably mounted, an enclosure in which the spindle is housed, an opening/closing mechanism such as a cover configured for opening to provide access to the spindle and for closing to contain particles that may be generated during operation of the device, and a seal configured for sealing the enclosure when the opening/closing mechanism is closed. The device may further include a pre-loaded hinge coupling the cover with the enclosure, and a loading mechanism such as a spring coupled with the hinge and configured for biasing the cover to a closed position and for applying a sealing force to the seal at an interface of the cover and the enclosure. This type of device may be implemented for use in an archival data storage system library such as in a cleanroom storage system.

The present disclosure relates to electronic devices that include a composition that actively generates a gaseous oxidizing agent component within the interior gas space of the electronic device. The present disclosure also involves related methods.

The present invention belongs to the technical field of hard disk device, and specifically relates to a Hard Disk Device Based on Blockchain. The hard disk device comprises a storage unit and a protection unit; wherein a hard disk body stores information in the blockchain; the protection unit comprises a protective case, an airbag and an interface extension board; the airbag is laid flat on the inner bottom of the protective case; the interface extension board passes through a side wall of the protective case and is bolted to the protective case; a dust board in a first through hole of the interface extension board is located at the port on the interface extension board close to the hard disk body when the hard disk body is not placed in the protective case; the dust board is connected to the inside of the first through hole by a first spring.

Case accessories for portable electronic devices are disclosed. In some embodiments, a case accessory may include a base configured to sit on a working surface, a support coupled to the base and configured to support a portable electronic device in an elevated position, a rotational mechanism coupled to the support configured to allow the holder to rotate in one or more directions relative to the support, and a holder coupled to the rotational mechanism and configured to secure the portable electronic device.

A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N.sub.2. The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.

An issue facing shared read/write player hard disc drives (HDDs) is when a head-media contact event occurs, any resulting plume of debris caused by the contact event not only affects the magnetic disc currently being read or written, but other magnetic discs within the HDD enclosure. The presently disclosed technology is directed as mitigating the potential consequences of such a head-media contact event. By providing one or more internal access doors within the HDD, a magnetic disc currently being read from or written to may be physically isolated from other magnetic discs within the HDD. As a result, in the event of a head-media contact event, any resulting plume of debris caused by the contact event only affects the magnetic disc currently being read or written. The remaining magnetic discs within the HDD are isolated from the plume of debris.

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.

A device includes a cover and a base. The base is coupled to the cover to create an enclosure. The device also includes a form-in-place-gasket. The form-in-place-gasket is positioned between the cover and the base to create a seal. The form-in-place-gasket includes an acid-absorbing material.
