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.

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.

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 presently disclosed technology is directed to maximizing cleanliness, reliability, and space efficiency within a jukebox-style HDD, while minimizing overall cost of the HDD. In an effort to reduce the movement of a robotic arm assembly, cassettes within a jukebox-style HDD may be configured to be magnetically repositionable to replace some of the movement of the robotic arm assembly, without adding another significant source of potential mechanical failure within the HDD enclosure. Further, the overall number of moving parts is reduced, which may improve reliability of the HDD, as well as cleanliness within the HDD enclosure.

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.

Disclosed herein are sliders with segmented front bars, methods of manufacturing them, and data storage devices comprising them. In some embodiments, a slider comprises a segmented front bar, a leading pad, a shallow-edge surface, and a cavity. The segmented front bar includes a plurality of slots situated substantially perpendicular to the leading-edge surface of the slider. The leading pad is situated between the leading-edge surface of the slider and a trailing edge of the slider and is recessed from the segmented front bar. The cavity abuts the segmented front bar and is situated between the segmented front bar and the leading pad. The shallow-etch surface is situated between the cavity and the leading pad. A maximum depth of the plurality of slots relative to a non-recessed surface of the segmented front bar is less than a depth of the cavity relative to the non-recessed surface of the segmented front bar.

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.
