ABSTRACT:
A method of producing an optical disc of bonded type includes the processes of: (A) forming a first reflection film, which is half transparent for partially reflecting and partially transmitting an incident light, on a first information record surface of a first transparent substrate; (B) forming a second reflection film, which has a reflective index higher than that of the first reflection film, on a second information record surface of a second transparent substrate; (C) dripping a liquid resin of ultraviolet hardening type onto one of the first and second reflection films by a spin coating method to form a first resin layer in a non-hardened condition; (D) dripping a liquid resin of ultraviolet hardening type onto the other of the first and second reflection films by a spin coating method; (E) emitting ultraviolet onto the liquid resin dripped by the process (D) to form a second resin layer of ultraviolet hardening type in a hardened condition; (F) provisionally bonding the first and second transparent substrates together in a pressure reduced environment; and (G) hardening the first resin layer by emitting ultraviolet from a side of the first transparent substrate.
