REVERSIBLE MEDIA FOR RECORDING OPTICAL INFORMATION

The current status, the prospects for development, and the advances of the State Optical Institute in the area of reversible optical recordi ng media are examined. Problems of light sensitivity, noise, and micro defects, as well as questions concerning cyclicity, memory, sensitomet ry, and structurometry are analyzed. The prospects for using the media (electrophotographic, photothermoplastic, and electro-optic media and media based on phase transitions in vanadium oxides) in optical syste ms for recording, storing, processing, and reproducing information are described.
