摘要： A data storage tape cartridge includes a housing having a reel within and rotatably supported by the housing. Two or more data storage tapes are wound up on the same rotary axis of the reel. Each subsequent winding of a first one of the tapes is separated from the previous winding of the first tape by at least another one of the other tapes. A leader pin is attached to a free end of each of the tapes. The leader pins may be connected to one another. The leader pins may be disconnected from one another as part of process for mounting the cartridge in a tape drive.

摘要： A tape cartridge for increasing tape drive head performance is provided. The tape cartridge comprises a cleaning tape, a tape guide arrangement that guides the cleaning tape within the cleaner cartridge, a cleaning fluid application arrangement that applies cleaning fluid to the cleaning tape within the cleaner cartridge, and a cartridge memory that stores cleaning count and motor taches count information. The tape guide arrangement is operable to bring the cleaning tape in contact with the cleaning fluid application arrangement to apply the cleaning fluid onto the cleaning tape when the cleaning tape is subject to a first tension level and avoid the contact with the cleaning fluid application arrangement when the cleaning tape is subject to a second tension level to prevent application of the cleaning fluid onto the cleaning tape.

摘要： 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.

摘要： The invention relates to a tape drive, and to a method and a computer program product for operating a tape drive. The tape drive may include a transport mechanism which may include a tape head. The tape drive may be adapted to receive a magnetic tape with the transport mechanism, and to transport the magnetic tape by the transport mechanism. The tape head may be adapted to perform read-write operations on an oxide side of the magnetic tape. The tape drive may include a burnishing unit, which may include a burnishing roller and a burnish controller having an abrasive shell. The burnishing roller may be installed in the tape drive upstream of the tape head such that the abrasive shell supports the received magnetic tape on the oxide side. The burnish controller may be adapted to control the movement of the burnishing roller.

摘要： A tape cartridge for a magnetic tape may be provided. The tape cartridge includes a magnetic tape surrounded by a housing and a temperature indicator that signals a temperature of the tape cartridge, for example, by a thermochromic label. Additionally, a system for tape cartridge data protection that interoperates with the tape cartridge is provided. The system includes a storage for holding a tape cartridge, a sensor that detects temperature information from the temperature indicator of the tape cartridge, and a control unit for controlling an actuator that performs an action depending on the detected temperature information. Furthermore, a method for operating the system for tape cartridge data protection is proposed.

摘要： A tape drive includes a plurality of rollers, a head, a tension sensor, and control circuitry. The rollers are spatially arranged within the tape drive to define a route for tape of a received data cartridge to travel from the received data cartridge to a tape reel. The head includes read elements and write elements configured to read from and write to the tape as tape of the received data cartridge travels along the route. The tension sensor is configured to measure tension of the tape as it travels along the route. The control circuitry is configured to cause a motor to impact the tension to keep the tape within a tension threshold.
