Abstract:
In order to realize (A) an optical information recording medium in which information is stored in high density and can be precisely and securely reproduced, (B) a method for reproducing the optical information recording medium, and (C) an optical information processing apparatus using the optical information recording medium, an optical information recording medium 1, 2, or 3 of the present invention includes: (a) a substrate 12, having pits and/or grooves, each of which is made up of a rise and a recess, and each of which corresponds to recorded information that is optically reproduced by irradiation of a light beam; and (b) at lease one super resolution reproducing film 13, which has an optical property to be changed in response to a temperature increase caused by the irradiation of the light beam, the optical property of the super resolution reproducing film being reversibly changed depending on a temperature change in the super resolution reproducing film. The optical information recording medium 3 of the present invention further includes a recording layer.
