The invention discloses a disc library storage system including a disc library, a disc drive tower and a disc transport device. The disc library is for placing multiple discs. The disc drive tower includes multiple disc drives for reading/writing data. The disc transport device is used for moving the discs to the disc drive tower from the disc library and moving the discs to the disc library from the disc drive tower.

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 system includes a processor and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, or integrated with and executable by the processor. The logic is configured to receive a request to store data on media and obtain a data key. The logic is configured to generate an encryption encapsulated data key using the data key and generate a session encrypted data key using the data key. The logic is further configured to provide the session encrypted data key to a machine configured to write encrypted data to the data storage media for use by the machine in writing encrypted data to the data storage media. The logic is configured to provide the encryption encapsulated data key to the machine for enabling the machine to store the encryption encapsulated data key with the data on the data storage media.

A data-storage system comprises a head receiver configured to variably receive up to a number M of write heads. The data-storage system also includes an installed number N of write heads arranged in the head receiver, a substrate receiver configured to receive one or more data-storage substrates, and a positioner machine configured to adjust a relative placement of each of the M write heads with respect to at least one of the one or more data-storage substrates.

A port is used for exchanging removable media with a media library. The port includes a port housing with an opening exchanging the media between an internal volume and another opening permitting an exchange of the media between the internal volume and the media library. The port also includes a guiding funnel for guiding the media from the environment to the opening, an elastic element and a plate for receiving the medium. The elastic element and the plate are installed in the internal volume, and the plate is coupled to the elastic element. The elastic element is configured for pressing the plate against the opening to seal the port when the plate is unloaded and for permitting a movement of the plate into the internal volume to allow the exchange of the medium through the other opening when the plate is loaded.

A disc cassette includes a curved portion configured to hold multiple discs. A platform portion abuts the curved portion. A movable bale is configured to maintain discs securely in the disc cassette except when rotated off the discs.

Embodiments for predetermining optimal demount position for demounting data storage cartridges in an automated data storage library by a processor. A selected demount position may be predetermined, while performing one of a plurality of robotic movements by an accessor, for each mounted data storage cartridge for demounting data storage cartridges in the automated data storage library. The selected demount position is recalculated for each mounted data storage cartridge for demounting the data storage cartridges while performing a subsequent demount operation, where the selected demount position is determined according to the recalculation prior to a demount command being issued. Accordingly, the idle time of the accessor during a demount operation may be reduced.

A method according to one embodiment includes receiving a request to store data on media, and generating a data key. An encryption encapsulated data key is generated using the data key. A session encrypted data key is generated using the data key. The encryption encapsulated data key and session encrypted data key are provided for use in writing encrypted data to the media. A method according to another embodiment includes receiving a request to read data from media, and receiving an encryption encapsulated data key. The encryption encapsulated data key is processed to obtain a data key. A session encrypted data key is generated using the data key. The encryption encapsulated data key and session encrypted data key are provided for use in reading the encrypted data from the media.
