Principles of Optical Disc Data Storage Slides

Abstract:  Everyone is familiar these days with Compact Disc (CD) and Digital Versatile Disc (DVD) systems.  In case familiarity has bred contempt for these marvels of modern technology, we will try to explain in simple terms the complex set of ideas and techniques that have made possible the construction of these Optical Data Storage devices.  Information, be it analog (such as voice, still images, video) or digital (e.g., text, computer files, internet traffic) can be represented in binary format as a string of 0's and 1's.  These binary strings can be stored on optical disks and retrieved (for reproduction) using lasers and other sophisticated opto-electronic instruments.  In this presentation we describe methods of conversion of the various forms of information into binary sequences, discuss methods of storing these sequences on CD and DVD platters, and explain how this information is recovered/reconstructed during playback.
