Paper Abstract

This paper reviews the optical principles upon which ultra-high resolution optical readout is predicated. Several different recorded geometries and optical readout techniques are discussed. The discussion includes a description of focus and track sensing techniques and photodetector configurations. As an example of these optical principles the application of optical information retrieval to the quality control and monitoring of electromechanically mastered VideoDiscs is detailed and optical-readout performance assessed.
