ABSTRACT:
A system and a method of recording information by changes of refractive index and light absorption coefficient on a thin film, and reproducing the recorded information by
scanning a focussed monochromatic light along a track on a thin film of a selected thickness and
letting a light component reflected at a light-incident surface of said thin film and the other light component reflected at an inside face of the opposite surface to said incident surface of the thin film interfere with each other thereby efficiently to vary intensity of reflection light.
