PROBLEM TO BE SOLVED: To surely discriminate front side/rear side on the outside appearance and to prevent a user from being in contact with a reproducing surface by sticking a first disk plate with a second disk plate and providing a pearl luster on the second disk plate. SOLUTION: An auxiliary disk plate 3 is overlapped on a protection film 7 side of a reproducing disk plate 2. Then next, the auxiliary disk plate 3 is stuck to the reproducing disk plate 2 by curing adhesive 8 by irradiating with ultraviolet rays, and a DVD1 is completed. By such a DVD1, the reproducing disk plate 2 having a substrate 4 is stuck to the auxiliary disk plate, formed by a resin mixing at least two kinds of plastics with different refractive indexes, and since the auxiliary disk plate is provided with the pearl luster, the front side/rear side is discriminated surely. |
