Abstract
There is provided a method and device for reading, writing, or both, data from or to a pattern recognition type optical memory having a light transmittable substrate. Patterns can be formed in the pattern recognition type optical memory from light images representing the data. An optical memory reading device comprises a light source, an image detecting unit for detecting images corresponding to the patterns and generating image signals converted by an optical/electric converter into electric signals. An optical memory writing device comprises a light source, an electric/optical converter for receiving an electric signal corresponding to the data and converting the electric signal into an image signal, and an image generation unit for receiving the light emitted from the light source and the image signal and generating light images corresponding to the image signal, wherein the images are configured to form the patterns on the light transmittable substrate.
