Q. Illustrate about Optical Memories?

In 1983 one of the most successful consumer products of all times was introduced which is compact disk (CD) digital audio system. This CD was a non-erasable disk which could store more than 60 minutes of audio information on one side. Huge commercial success of this CD enabled development of low-cost optical-disk storage technology that has revolutionised computer data storage. Some optical-disk systems has been introduced. We briefly review each one of these.
