ABSTRACT:
An optical information recording medium, which is made of a resin provided with photoreactivity containing organometal compound, has a recording layer on which, after a photoreaction are brought about when predetermined initialization light is irradiated to the medium and then the resin is hardened, at a time of recording information, a recording mark is formed when predetermined recording light is condensed to the medium, and a temperature of the medium near a focal point of the recording light is increased and the organometal compound is transubstantiated, and at a time of reproducing information, the information is reproduced based on returned light according to predetermined reading light being irradiated.
