Abstract: A novel rewritable optical information recording medium having a recording layer consisting of an organic dye film and capable of reversibly recording/erasing information by laser beam irradiation. A novel rewritable optical information recording medium having as a recording film at least one layer of organic dye film consisting of 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 is recorded by a local physical change by recording laser ray irradiation, data is reproduced by detecting the returned optical intensity change of a reproducing laser beam less powerful than a recording laser beam, and data is erased by at least one application of a continuous beam or a pulse beam more powerful than a reproducing laser beam and less powerful than a recording laser beam. A physical change involves a shape change.
