摘要： Disclosed is an optical memory playback apparatus using an electroluminescent semiconductor element as a combination light source and sensor, which apparatus permits information in an information storage medium to be reproduced in the form of variation in electrical characteristics of the semiconductor element by causing a beam of light issuing from the electroluminescent semiconductor element to be directed to the information storage medium, allowing the light reflected by the information storage medium to impinge on the semiconductor element for thereby inducing variation in the optical and electrical characteristics of the semiconductor element owing to the self-coupling effect.
