An archival data storage system library includes magnetic-recording disk media, a storage enclosure in which the media are housed, data storage devices (DSDs) configured to write to and read from the media, an automated disk handling mechanism configured to transfer at least some of the media between the storage enclosure and the DSD, and a hermetic enclosure containing the foregoing components. The storage system may further include a gas circulation system for filtering contaminants from the hermetic enclosure. Such a storage system may be implemented as a rack-mountable unit, or as an entire cleanroom facility, as well as in intermediate form factors between those. In the context of a cleanroom storage system, the system may further include an automated disk handling shuttle to receive the media from the disk handling mechanism and an automated disk loading mechanism for accessing the media from the shuttle for installing into the DSD.

An electronic module ejecting mechanism includes a frame, a door pivoted to the frame, a rod, a sliding sheet slidably disposed on the door, a swing sheet, and a button connected to the sliding sheet. An electronic module is inserted into an opening of the frame. The rod is slidably disposed in the frame and has groove and bending ends. The swing sheet is pivoted to the sliding sheet and has a latch end for inserting into the groove end when the sliding sheet slides to a lock position. When the latch end is inserted into the groove end and the swing sheet swings to an expanding position with opening of the door, the latch end pulls the groove end to make the bending end push the electronic module to partially protrude from the opening. When the door continues opening outwardly, the latch end is separate from the groove end.

An object of the present invention is to provide a cassette shutter in which the durability of a curved shutter for opening and closing a medium entrance of a cassette is improved, and assembly of parts is simple. In the present invention for achieving said objective, a cassette shutter, which is slidably disposed on front and bottom surfaces of a cassette storing a paper medium therein and opens and closes an entrance formed in the front surface of the cassette, is configured to include: a plurality of pieces arranged longitudinally and a fastening pin that passes through and thereby fastens a lower portion of an upper-side piece and an upper portion of a lower-side piece so as to enable relative rotation of the plurality of pieces.

To improve general versatility regarding a disk cartridge. A disk conveyor apparatus includes: a disk holder that holds at least a part of a disk cartridge in which disk-shaped recording media are accommodated inside a case body in a state where the disk-shaped recording media are accommodated, and is moved in at least a direction of a center axis of the disk-shaped recording media; a movement mechanism that causes the disk holder to move in the direction of the center axis of the disk-shaped recording media; and a feeder mechanism that feeds the disk-shaped recording media toward a disk drive apparatus from the case body, the disk holder being capable of holding different types of disk cartridges, a movement position of the disk holder being set by operating the movement mechanism in accordance with the type of the disk cartridge.

A cam projection sliding in a cam slot of an arm causes the arm to proceed to an arm when a shutter is in the closed position or the open position and to recede from the arm when the shutter is sliding between the open position and the closed position. A spring is thereby considerably displaced, providing a satisfactory operation of the shutter.
