摘要： PROBLEM TO BE SOLVED: To provide a new rewritable optical recording medium having a recording layer comprising an organic dye film and capable of reversibly recording/ erasing information by laser beam radiation. SOLUTION: The new rewritable optical information recording medium having as a recording film at least one layer of organic dye film comprising practically at least one kind of organic dye compound. Information is recorded and erased by reversible physical changes caused by laser beam irradiation on an organic dye film single element. Specifically, data are recorded by a local physical change by recording laser ray irradiation, data are reproduced by detecting the returned optical intensity change of a reproducing laser beam less powerful than a recording laser beam, and data are erased by at least one application of a continuous beam or a pulse beam more powerful than a recording laser beam and less powerful than the recording laser beam. A physical change involves a shape change. COPYRIGHT: (C)2004,JPO
