Abstract: Data cartridge detection systems and methods. An embodiment of a method comprises detecting a signal reflected from a data cartridge in a picker assembly. Moving the picker assembly after a loading operation only if the detected signal indicates the data cartridge is engaged in the picker assembly. The method may further comprise moving the picker assembly after an unloading operation only if the detected signal indicates the data cartridge is disengaged from the picker assembly.

Abstract: A method of displacing a media holder assembly of a media autochanger between a first rotational registration position and a second rotational registration position.

Abstract: Shipping lock apparatus for securing a moveable cartridge picker assembly to a frame may comprise a lock member mounted to the cartridge picker assembly so that the lock member can be moved between a locked position and an unlocked position. A thumb assembly contained within the cartridge picker contacts the lock member as the thumb assembly moves to a retracted position so that the lock member is moved to the unlocked position when the thumb assembly reaches the retracted position. A slot associated with the frame engages the lock member when the cartridge picker assembly is located at a stowed position and when the lock member is placed in the locked position.

Abstract: An apparatus and method for detecting a data cartridge in a cartridge engaging assembly. A signal emitter may be positioned adjacent the cartridge engaging assembly to emit a signal. A signal detector mounted to the cartridge engaging assembly may detect the signal. The signal detector generates output to indicate whether the data cartridge is present in the cartridge engaging assembly based on the detected signal.
