Abstract: A library for storing a cartridge of data-storage media includes a removable module and a chassis having a module receptacle. Cartridge storage slots are disposed within the chassis, and a media drive is disposed within the removable module. A cartridge transporter is disposed within the chassis and transports the cartridge between one of the cartridge slots and the media drive when the module is inserted within the module receptacle. A library control circuit is disposed within the chassis and controls the cartridge transporter. An interface circuit is disposed within the removable module and electronically interfaces a host computer to the media drive, and, when the removable module is inserted within the module receptacle of the chassis, electronically interfaces the host computer to the library control circuit.

Abstract: A library for storing a cartridge of data-storage media includes a chassis and includes cartridge slots, a media drive, a cartridge transporter having a cam mechanism, and transporter and cam drive assemblies all located within the chassis. The cartridge slots each have an outer slot opening that faces outward of the chassis and an inner slot opening that faces inward of the chassis, and each slot allows insertion and removal of the cartridge through both of the respective inner and outer slot openings. The media drive has a cartridge opening that faces the inner slot openings and receives and ejects the cartridge via this opening.

Abstract: A library for storing a cartridge of data-storage media includes a chassis having a plurality of walls that each have inner and outer sides. A cartridge storage receptacle is mounted to the inner side of a first of the walls and has a receptacle port facing away from the first wall. A cartridge mailbox is mounted within an port that is formed in a second of the walls. The mailbox has a slot with a first slot port accessible from the inner side of the second wall and a second slot port accessible from the outer side of the second wall. The slot is constructed to allow insertion of the cartridge into the slot via the first and the second slot ports, and to allow removal of the cartridge from the slot via the first and the second slot ports. An x-y drive assembly is mounted within the chassis. A cartridge picker is mounted to the drive assembly and has a first picker port and a second picker port.

Abstract: A data storage unit includes multiple media processors that are each moveable between a transfer position and a corresponding standby position, and are able to receive a storage medium. A shuttle assembly moves a selected one of the media processors between the transfer position and the corresponding standby position. A magazine is provided with a plurality of compartments that are each able to receive a storage medium. A magazine drive assembly moves the magazine so as to move a selected one of the compartments into the transfer position. A transfer assembly transfers a storage medium between the selected media processor and the selected compartment while the selected media processor and the selected compartment are in the transfer position. A controller controls the operations of the shuttle assembly, magazine drive assembly, and transfer assembly.

Abstract: A computer storage unit usable with DAT cassettes. The unit has a tape drive, a carriage that is movable laterally relative to the tape drive opening, and a magazine having slots sized to releasably hold the cassettes therein. The magazine is releasable attachable to the carriage. A pair of gripper arms is rotatably mounted at the end of an arm attached to a traveler which moves the gripper arms between a selected magazine slot and the tape drive opening. The gripper arms are rotatable between a grasping position, a pushing position and an open position using a solenoid-driven actuator arm which linearly moves a head block to which the gripper arms are loosely connected at a position offset from their axis of rotation. A sensor is used in conjunction with the gripper arms to selectively move the cassettes during a test cycle to determine if cassettes are present in the magazine slots and whether the cassettes are in backwards.

Abstract: A typesetting terminal adapted for operating a photo typesetter includes a data processor with a plurality of peripheral devices coupled thereto, such as a keyboard, cathode ray tube display, cursor control and a plurality of tape transports. Information from the keyboard and selected tape transports is read into the data processor memory for access and display by the cathode ray tube and outputting to a further tape device. Desired information can be searched in the various input tapes for display, editing and combination with information derived from another input.
