In order to increase storage capacity and data transfer rates, a sophisticated signal processing technology − multilevel technology − has been developed. To demonstrate the advantages of this novel technology, a multilevel (ML) optical data storage system that triples the capacity and transfer speed of CD systems has been realized. This article explains not only the basic system concept but also describes how the ML system has met the margins required for existing manufacturing processes.
