Abstract
A system for producing disc-like optical data carriers comprises an injection-molding machine for manufacturing a disc-like substrate, and a finishing device for applying a reflective layer to the substrate and for applying a protective layer to the reflective layer. The injection-molding machine and the finishing device are integrated in a single production unit. An optical inspection unit is also integrated in the production unit.
