发明名称 Disc-molding mold, mirror-surface disc, and method for producing mold for disc molding
摘要 An object is to improve the durability of a mold and reduce the cost of the mold. A disc-molding mold includes a first mold; and a second mold disposed in opposition to the first mold such that the second mold can advance and retreat. One of the first and second molds includes a base material having a roughened surface, and a coating layer formed on the surface of the base material through coating treatment. A stamper attachment surface is defined on a surface of the coating layer. Since a coating layer is formed on the roughened surface of the base material through coating treatment, the area of contact between the base material and the coating layer can be increased. Therefore, the adhesion force between the base material and the coating layer increases, so that the coating layer becomes unlikely to peel off, whereby the durability of the mold can be improved, and the cost of the mold can be reduced.
