摘要： An automated storage library having the ability to store and manipulate data storage elements in three dimensions. Data storage elements such as tape cartridges are stored in storage compartments separated by low-friction downward sloping sliding planes each capable of holding a plurality of data storage elements. The automated storage library further includes a magnetic picker apparatus having two electromagnetic coils. In one embodiment, the two coils are energized simultaneously with the first coil used to reposition an L-shaped flipper. This flipper raises a roller gate positioned at one end of a storage compartment to release a stored data storage element. The second electromagnetic coil supplements the gravitational pull on the data storage element by attracting a steel strip on the face of the data storage element and an associated coil carriage retrieves the data storage element from the compartment.

摘要： An interlock system is provided for removable-media drive unit to prevent the drive loader from attempting to pull in and mount a data cartridge before it is released by a mechanical gripper or human hand. The interlock system includes a light source and a photodetector positioned in front of the drive on opposite sides of the path cartridge takes when it is being inserted or removed from the drive loader. The presence of the cartridge, gripper or other object in the path interrupts a light beam from the light source thereby signalling the drive controller to disable the drive loader. When the gripper has released the cartridge and withdrawn, or when the path is otherwise clear, the photodetector again detects the light beam and signals the drive controller that the loader can be safely enabled. In one embodiment, the light source and photodetector are mounted on a card which plugs into the face of the drive. The presence of the card indicates to the drive controller that the drive is installed in a library environment and causes the drive controller to execute appropriate program code to interpret signals from the photodetector and enables and disables the drive loader in response.
摘要翻译：为可移动介质驱动单元提供互锁系统，以防止驱动装载机在机械夹持器或人手释放之前尝试拉入并安装数据盒。互锁系统包括光源和位于驱动器前方的光电检测器，该光电检测器在从驱动装载机插入或移除时位于路径盒的相对侧上。存储器，夹子或其他物体在路径中中断来自光源的光束，从而发出驱动控制器以禁用驱动装载器。当夹具已经释放墨盒并取出时，或者当路径清除时，光电检测器再次检测光束并向驱动控制器发出信号，指示加载器可以被安全地启用。在一个实施例中，光源和光电检测器安装在插入驱动器表面的卡上。卡的存在向驱动器控制器指示驱动器安装在库环境中并且使得驱动器控制器执行适当的程序代码来解释来自光电检测器的信号，并且响应地启用和禁用驱动器装载器。
