A disc library storage system and a disc cartridge thereof are provided. The disc library storage system includes a disc library, a disc drive tower, a disc transport device and a disc changing device. The disc library accommodates multiple discs. The disc drive tower accommodates multiple disc drives. The disc drives read data of the discs. The disc transport device moves the discs from the disc library to the disc drive tower and to the disc library. The disc changing device places a disc cartridge including an outer casing and a disc tray. The disc tray accommodates at least one replacement disc. The disc changing device has a pull-out state, in which the disc tray is received in the outer casing, and a close state, in which the disc tray is drawn from the outer casing and the disc transport device unloads the replacement disc from the disc tray.

Storage systems and methods to provide high-density data storage. Freestanding storage servers include storage drives, left and right backplanes, a backing plate, host adapters, and cables. The left and right backplanes are secured to the backing plate. The mounting holes of each storage drive attached to the left backplane are bilaterally symmetrical about a median plane to the corresponding mounting holes of each storage drive attached to the right backplane. Each left and right backplane has plug receptacles which are aligned and coupled to cables. The plug receptacles of the left backplane are bilaterally symmetrical about the median plane to corresponding plug receptacles of the right backplane. Host adapters are aligned, and each has plug receptacles, organized into a left and a right connector group, which are coupled to cables. For each host adapter, the left connector group is bilaterally symmetrical about the median plane to the right connector group.

A data storage library includes multiple storage cartridges arranged on a rack; read/write control electronics integrated within a media player assembly; and actuation means for achieving relative movement between media player assembly and the multiple storage cartridges in the rack to allow the read/write control electronics within the media player assembly to selectively couple with and provide data access to at least a subset of the multiple storage cartridges.

A data storage library includes a number of storage cartridges arranged in a rack accessed by a actuated media player. The actuated media player is adapted to move the along a plane relative to a fixed subset of the storage cartridges in the rack to and to selectively couple to each storage cartridge of the fixed subset to facilitate selective read/write access.

A hard drive storage device comprises a hard drive enclosure (10) configured to accommodate a hard drive (20), and a hub (30) disposed in the hard drive enclosure (10). The hard drive (20) is electrically connected to the hub (30). The hub (30) comprises two or more USB interfaces (31) arranged at a side wall of the hard drive enclosure (10). The hard drive storage device integrates together a storage functionality of the hard drive and a data interface expansion functionality of the hub, and is easy to use and carry.

A server box embodiment is disclosed that generally comprises an array of dummy HDDs that share a common set of universal disk drive components in a master components module, or power module. Each dummy HDDs is constructed without expensive onboard chipsets that control the normal functionality of a standard HDD. By sharing expensive chipsets in a master components module (power module) money can be saved in building and selling the dummy HDD server. Embodiments envision a power module possessing the needed chipset functionality that is missing in a dummy HDD. The power module can be made to move from dummy HDD to dummy HDD supplying the necessary chipset in a shared manner when data is being stored or retrieved for client or end-user.

A hard disk storage device includes a hard disk box configured to accommodate a hard disk body, and a hub arranged in the hard disk box. The hard disk body is electrically connected to the hub. The hub is provided with two or more USB interfaces. The USB interfaces are arranged on a side wall of the hard disk box. The hard disk storage device integrates a storage function of the hard disk and a data interface extension function of the hub, and is convenient to use and carry.

An opening and closing device of rotating cage type jukebox disc tray including a first disc tray carrying discs and an opening and closing mechanism of disc tray including a first linkage mechanism and a first driving device is provided. The first linkage mechanism includes a first linkage bar, a first sliding member and a second linkage bar. The second linkage bar is slidingly disposed on the first sliding member which is slidingly disposed on the first linkage bar. When an end portion of the second linkage bar is connected to a first ear portion on a lateral side of the first disc tray, the first driving device drives the first sliding member to slide on the first linkage bar, leading the second linkage bar to slide on the first sliding member and thereby leading the first disc tray to rotate around a first fixing post.
