Abstract
Disclosed is an optical disk handling system having two control systems to provide the motions necessary to move optical disk cartridges form storage holding cells to an optical drive. During initialization, the cartridge handling system uses shaft encoders, along with current or voltage feedback from the motors, to calibrate the home locations of the mechanisms. The system determines the home position for vertical movement of the transport as well as the top and bottom positions used for the translate operation. The system then calibrates the plunge movement, the flip movement, and the translate movement. Finally, the system determines whether the path for all the movements is free of obstructions.
