A removable mechanism for a hard drive is revealed. The removable mechanism includes an upper substrate and a base plate hanged and sliding below the upper substrate, and a control handle and a sliding board are set between the upper substrate and the base plate to carry each other. The control handle controls a pivot element sliding on an opening of the base plate. By carrying each other to carry a stop element of the base plate, the stop element slides on a concave opening for dismounting a storage device inserted to the removable drawing mechanism. Thereby, the present application is convenient for dismounting the storage device.

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 storage system for continuing I/O without affecting drive box addition to a host computer includes: a plurality of drive boxes for connecting to a computer device that transmits commands for data reads or writes; and a storage controller connected to the drive boxes. A first drive box provides a first storage region to the computer device. The storage controller manages correspondence between the first storage region and a physical storage region of the drives constituting the first storage region. The first drive box receives a command for the first storage region from the computer device and transfers the command to the storage controller. The storage controller generates a data transfer command including a data storage destination based on the address management table, and transfers the command to the first drive box. The first drive box then transfers the data transfer command to the second drive box.

A load/unload ramp assembly for a hard disk drive includes a support plate having at least one interlock slot and a plurality of ramp units interconnected with the support plate. At least one of the ramp units includes an interlock structure that protrudes into a corresponding interlock slot of the support plate, and is configured to move within the interlock slot in response to shrinkage of the ramp unit upon cooling associated with manufacturing of the ramp assembly. The ends of the interlock slot may be configured to manage the shrinkage and/or to maintain design dimensions.

A packaging container for a multimedia storage carrier includes a panel portion and a peripheral side portion. The panel portion is arranged in the peripheral side portion in a sunken manner, and an inner cavity for accommodating the multimedia storage carrier is defined by the panel portion and an inner wall of the peripheral side portion. An inner edge of the peripheral side portion is provided with a snap portion and a snap groove portion opposite to the snap portion. The snap portion and the snap groove portion are configured to fix the multimedia storage carrier in the inner cavity. The snap portion is provided with a support member that abuts against a bottom surface of the multimedia storage carrier, and the support member is configured to support the multimedia storage carrier.

[Object] A cartridge memory according to an embodiment of the present technology is a cartridge memory for a recording medium cartridge, including: a memory unit; and a capacity setting unit. The memory unit has a memory capacity capable of storing management information relating to a second information recording medium configured to be capable of recording information with a second data track number larger than a first data track number. The capacity setting unit is configured to be capable of setting a data storage area limited to a first capacity capable of storing management information relating to a first information recording medium configured to be capable of recording information with the first data track number.

A data storage disk cartridge library includes a media drive having a clean internal environment, a disk cartridge bay positioned adjacent to the media drive, and a disk cartridge positioned in the disk cartridge bay and having clean compartments for housing a clean disk trays supporting clean magnetic recording disk media. The media drive has a disk tray extractor including a seal plate positioned at times flush with a surrounding shroud, and a set of pins for extending through the seal plate and a disk tray and for moving to a tray locking position. The seal plate covers a disk tray faceplate to physically isolate the faceplate from the clean portion of the disk tray, the corresponding clean compartment, and the clean environment of the media drive. The shroud is configured to cover surfaces of the disk cartridge adjacent to the faceplate.

A recording and reproducing device includes: a first acquisition unit which acquires servo band interval information representing an interval, in a width direction of a magnetic tape, between adjacent servo recording elements of plural servo recording elements which record the servo patterns on the plural servo bands, respectively; a second acquisition unit which acquires reproducing element interval information representing an interval in the width direction between respective servo reproducing elements which read the adjacent servo patterns along the width direction with respect to the plural tape drives; and a selection unit which selects a tape drive into which the magnetic tape is inserted, from the plural tape drives, using a value representing a difference between the interval represented by the servo band interval information and the interval represented by the reproducing element interval information.
