Abstract:
A production process of an optical disk, comprising:forming a first metal thin film on a first substrate; forming a layer of an ultraviolet curing resin on the first metal thin film; forming a transparent molded substrate having a pattern transcribed thereon by injection molding in a same manner as a production process of the first substrate; forming a semi-transparent stamper by evaporating a semi-transparent film made of at least one metal selected from gold, silver, and aluminum onto the transparent molded substrate in a same manner as a production process of the first metal thin film; and curing the ultraviolet curing resin layer by irradiating ultraviolet rays through the semi-transparent stamper; forming a second metal thin film on the ultraviolet curing rein layer which has been cured; and forming a cover layer on the second metal thin film.
