摘要： Constructed is an optical recording medium which is so formed as to have excellent surface flatness and with respect to which information is recorded or reproduced with the use of a near-field optical system. The optical recording medium is one which performs at least one of recording and reproduction of information by irradiation of light. The optical recording medium has a substrate 1 which has fine concavities and convexities 2 formed on the surface on a side where irradiation of light is performed, and a formed film layer having at least a recording layer and having a fine concavities and convexities surface reflecting the fine concavities and convexities 2 in itself. The optical recording medium also has a light transmission flattenable film 4 which is so formed on the formed film layer as to have the fine concavities and convexities surface buried therein, and the surface of which is polished and which has a single-layer or a multi-layer structure having a hardness enabling the film to be polished, has a transmission characteristic with respect to the irradiated light to thereby permits transmission of a light irradiated with respect to this optical recording medium.
