ABSTRACT:
An optical recording medium contains a fluorescent material and a photo-reactive bistable quencher. Information is digitally recorded by utilizing the bistable isomers of the photo-reactive bistable quencher by irradiating the medium with a light in the wavelength to be absorbed by the fluorescent material, whereby energy is transferred from the fluorescent material to the photo-reactive bistable quencher. Reading is made by irradiating the medium with a weaker light and detecting the fluorescence emitted by the fluorescent material.
