    Abstract: A disk drive includes a disk rotating unit, a traverse base holding the disk rotating unit, a damper member holding the traverse base, a main unit holding the traverse base through the damper member, a tray mounting a cartridge housing the disk, a driving unit that loads or ejects the tray and moves the disk in the cartridge relative to the disk rotating unit, and a traverse base holding member that is moved vertically by the driving unit relative to the main unit at the time of tray loading or tray ejection. The traverse base is held by the traverse base holding member through the damper member, and the resonance frequencies of the damper member in the radius direction of the disk as it is being loaded and in the direction of a rotation shaft are set higher than the maximum rotational frequency of the disk.

    Abstract: 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.

    Abstract: The tray braking device includes a tray, a tray motor, a sliding plate and a buffer structure. The tray is used for carrying a disc. The tray motor is used for driving the tray to a finish position from a first position. The sliding plate is disposed on a base. The buffer structure is disposed between the sliding plate and the base. When the tray moves to a second position from the first position, the tray moves at a first speed, and the second position is positioned between the first position and the finish position. When the tray moves towards the finish position from the second position, the tray drives the sliding plate to move, such that the buffer structure leans between the sliding plate and the base and generates deformation, making the tray move at a second speed slower than the first speed.
