<p>An optical information recording medium (100, 120, 130, 140, 150), which is made of a resin provided with photoreactivity containing organometal compound, has a recording layer (101, 121, 131, 141, 151) on which, after a photoreaction are brought about when predetermined initialization light (L1, L21, L31, L51) 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 (L2c, L22c, L32c) is condensed to the medium, and a temperature of the medium near a focal point of the recording light (L2c, L22c, L32c) is increased and the organometal compound is transubstantiated, and at a time of reproducing information, the information is reproduced based on returned light (L3, L23, L33) according to predetermined reading light (L2, L22d, L32d) being irradiated.</p> |
