摘要:
Systems and methods are described for using topographic and/or contrast spot scanning to facilitate various types of functionality in context of a data storage library. A robotic mechanism includes a hand assembly that has one or more integrated spot scanners. The hand assembly is configured to travel in at least two directions and to rotate, thereby locating and/or pointing the spot scanner in desired locations throughout the data storage library. By sweeping the spot scanner across a scan window, contrast and/or topographic data can be acquired and decoded to generate a profile of a region. The profile can be interpreted to facilitate functions, such as calibration of robot location with respect to media cartridges, targeting, proximity detection, empty cell detection, etc.

Systems and methods are described for providing selective biasing of a platform in context of one or more modules. While moving in the Z-direction with respect to the modules, the platform travels in an unbiased manner. For example, one or more alignment features on the platform are engaged with one or more alignment features on the modules to allow the platform to substantially float within an X-Y region defined by the alignment features. When the platform reaches its desired Z-location, magnetic features bias the platform into a substantially locked and repeatable X-Y position (e.g., using permanent magnets and/or electromagnets). In some embodiments, the platform is locked into an accurate position to allow a robotic mechanism of a storage library to move around efficiently within the modules while still being able to perform operations that involve accurate positioning (e.g., pick and place operations on media cartridges).

Systems and methods are described for providing a magnetic clutch to limit Z-directional motion of a mass (e.g., a carriage for transporting a robotic mechanism in context of a storage library). According to embodiments, the mass is suspended by cabling, and its Z-directional movement is controlled by a Z-drive assembly. The Z-drive assembly includes a drive gear made of a magnetic or conductive material, and the drive gear is in magnetic communication with a biasing magnet. Embodiments configured the biasing magnet with a particular magnetic moment and a position relative to the drive gear, so that the spinning of the drive gear induces magnetic currents that tend to counteract the motion of the gear. For example, in the event of power loss to the Z-drive assembly, magnetic clutching is used to limit or prevent motion of the mass under the force of gravity.

The pass thru mechanism for automated cartridge library systems serves to interconnect two juxtaposed operationally independent automated cartridge library systems and provides a simple apparatus that makes use of gravity to obviate the need for complex mechanical mechanisms to pass the media cartridge between the juxtaposed automated cartridge library systems. In particular, the pass thru mechanism comprises a media cartridge receiver that accepts a media cartridge from an automated cartridge library robot and then deposits the media cartridge in a media cartridge positioning mechanism. The media cartridge positioning mechanism uses gravity to tumble the media cartridge down a ramp into a media cartridge transport that delivers the media cartridge to the robot located in the juxtaposed media cartridge receiving automated cartridge library system. The media cartridge positioning mechanism operates to reorient the media cartridge from a horizontal orientation to a vertical orientation while concurrently turning the media cartridge as it tumbles through its path to present the label end of the media cartridge to the robot that is located in the media cartridge receiving automated cartridge library system.

Systems and methods are described for providing sensing slack on cabling coupled between a drive mechanism and a carriage. Embodiments of the carriage are configured so that the cables are substantially in tension when Z-directional movement of the carriage is substantially unimpeded and at least one cable manifests slack when Z-directional movement is impeded. Accordingly, detecting slack on the cables can be used to detect impedance to Z-directional movement of the carriage. According to some embodiments, a novel slack sensor translates tension on the cables into a forward pulling force that holds the slack sensor in a deactivated state. A reverse force is maintained on the slack sensor in a magnitude and direction that causes the slack sensor to move to an activated state whenever sufficient tension is not manifest on the cables. Slack can thus be detected by detecting when the slack sensor is in its activated state.

Embodiments include systems and methods for securing a magazine in a housing using a latching system. Embodiments operate in context of a storage library having removable magazines that store data cartridges. For example, a floating, two-part latching system operates in either an operable state or an unlatched state. The latching system includes a setter and a latch, where the latch is configured to float on the setter and to be biased into a latched position. When the setter is in a first position, it permits the latch to float between at least a fully latched position and a fully unlatched position. When the setter is moved to a second position, it moves the latch into the fully unlatched position and restricts the latch from moving into the latched position.

Systems and methods are described for providing magnetic biasing of a carriage in context of linear guides. In one embodiment, a robotic mechanism is configured to travel on a platform assembly within a structural context. The platform assembly transports a carriage in a Z direction, and the carriage transports the robotic mechanism in an X direction. The carriage moves in the X direction along rails (e.g., and/or other types of linear guides) in a substantially floating or unbiased manner. For example, one or more alignment features on the carriage are in communication with the rails to allow the carriage to move relatively freely within an alignment region defined by the alignment features. When the carriage reaches its desired X location, magnetic features bias the carriage into a substantially accurate, secure, and repeatable position.
