The optical disc cartridge is a basic unit of a modern optical disc library, and a plurality of optical discs are usually accommodated in the optical disc cartridge, and the optical disc cartridge is in a closed and locked state at ordinary times. When the optical disc in the optical disc cartridge is required to be operated, the disc extractor on the optical disc cartridge manipulator is responsible for unlocking the optical disc cartridge and extracting the optical disc cartridge to the position where the disc extractor on the optical disc cartridge manipulator can vertically grasp the optical disc up and down. When the operation is completed, the drawer is also responsible for pushing the disc cartridge into the locked and closed positions. In order to increase the placement density of the disc cartridges in the disc library, the disc cartridges are typically placed in a disc cartridge bay disposed opposite to the horizontal plane. The robot arm of the optical disc library moves in the front-rear horizontal and vertical directions in the space where the horizontal surfaces are placed face-to-face so that each optical disc cartridge can be operated by the disc extractor and the disc gripper on the robot arm. Due to the width limitation of the modern standard 19 inch cabinet, after the optical disc cartridge is arranged opposite to the horizontal plane, the space left for the optical disc library manipulator to be positioned between the two optical disc cartridges is limited.
