Abstract: A safety system for online servicing of a media library is provided, wherein the library comprises a plurality of media storage cells and at least one media picker robot that moves along the media storage cells, and wherein the library is contained within an enclosure having at least one access means. The safety system detects whether the access means in the enclosure is open or closed and operates the robot in the media library in one of two corresponding modes. If the access means is closed, the robot operates in a normal mode at a first specified speed. If the access means is open, the robot operates in a safe mode at a second specified speed that is slower than the first speed of the normal mode. In another embodiment, while in safe mode, the picker robot is excluded from moving within a restricted zone in the library.

Abstract: A method and system for accessing media objects in an automated storage library using a robotic mechanism included mounting the robotic mechanism to a horizontally arranged track arranged in the same plane as first and second horizontal rows of media object storage cells. Each of the media object storage cells houses a media object. The horizontally arranged track is disposed adjacent to the first row of media object storage cells. The robotic mechanism is mounted to the track for moving horizontally along the track. A media object manipulation mechanism such as a gripper mechanism is coupled to the robotic mechanism. The media object manipulation mechanism is vertically movable for moving between the first and second rows of media object storage cells when the robotic mechanism is coupled to the track to manipulate the media objects housed within the first and second rows of media object storage cells.

Abstract: A system for identifying and managing information stored in a plurality of physical volumes (e.g., tape cartridges) in an information storage system includes a plurality of labels. Each label is configured for physical attachment to a physical volume and includes an electromagnetic transducer for storing data associated with the physical volume and/or the information contained therein. The means for storing is non-volatile, re-writable, and readable without requiring physical contact with the label.

Abstract: A system for identifying and managing information stored in a plurality of physical volumes (e.g., tape cartridges) in an information storage system includes a plurality of labels. Each label is configured for physical attachment to a physical volume and includes an electromagnetic transponder for storing data associated with the physical volume and/or the information contained therein. The electromagnetic transponder is non-volatile, re-writable, and readable without requiring physical contact with the label. The system includes a robotic hand assembly for manipulating the physical volumes. Fine positioning of the robotic hand assembly with respect to the physical volume is done based on a signal returned from the electromagnetic transponder.

Abstract: A method and device for storing and using information associated with multiple logical volumes stored on a single physical volume associated with a data storage system. The invention uses writable labels to read and write metadata associated with the multiple logical volumes. Metadata stored on a writable label associated with each physical volume is available without either reading the physical volume itself or accessing a host computer's control data set.

Abstract: A tape cartridge or other physical volume includes a housing configured to accommodate magnetic data storage media, such as a reel of magnetic tape. A magnetic field detector is coupled to the housing for indicating whether the housing has been exposed to a magnetic field of sufficient intensity to corrupt or bulk erase the magnetic media. In a first embodiment, the detector is implemented as a magnetic media element having a predefined pattern of magnetic domains recorded thereon. In a second embodiment, the detector is implemented with a magnetic film element having a predefined pattern of magnetic domains recorded thereon and a polarizing filter stacked on top of the magnetic film element to polarize light incident upon the magnetic film element. Based on the Kerr effect, light incident upon the magnetic domains will undergo a shift in polarization angle before being reflected back to the polarizing filter. Erasure or alteration of the magnetic domains will modify the polarization shift.
