ABSTRACT:
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.
