Optical Storage is made possible by data storage devices such as optical discs and holographic storage systems. In computing, a data storage device—as the name implies—is a device for storing data. ... In computing, sound reproduction, and video, an optical disc is flat, circular, usually polycarbonate disc whereon data is stored. ... In late 1995 a joint university/industry/government consortium initiated the Holographic Data Storage System (HDSS) programme, with the initial goals of developing several key components for the system, including a high-capacity, high-bandwidth spatial light modulator used for data input; optimised sensor arrays for data output; and a...
