摘要： An optical recording medium includes a main-information area in which a metal reflection film is formed on a substrate where a row of pits is formed as main data, and a sub-information area in which is recorded medium identification information, which is used to identify the optical recording medium individually, by removing the metal reflection film partially and forming a plurality of reflection-film removed areas. Information is reproduced by irradiating the metal reflection film with a beam of light. In the sub-information area, a row of pits or a guide groove is formed on the substrate, and a track pitch of the row of pits or the guide groove is at least 0.24 μm wide and at most 0.45 μm wide.

摘要： An optical information recording medium is manufactured by bonding a first substrate having a first central bore and a second substrate having a second central bore to each other with radiation cure resin. The radiation cure resin is coated on the first substrate. The first and second substrates are brought into close contact with each other so as to form the first and second substrates integrally with the radiation cure resin. A neighborhood of the first and second central bores is radiated. A whole of at least one of opposite outer faces of the integral first and second substrates is irradiated with radiation so as to wholly cure the radiation cure resin.
