Base CDs are stacked on an elevator system. The CDs include one side on which data is recorded, and another side on which the CD label is printed.

An image mapping program then determines the rotational orientation of the CD by comparing the picture and data image. Once the orientation of the disc is known, the robot arm rotates the disc a calculated amount so that it can then be placed on the cutting table in a proper normalized orientation. The CD is held in place on the cutting table by a vacuum chucking system.
