发明名称 OPTICAL INFORMATION RECORDING MEDIUM
摘要 PROBLEM TO BE SOLVED: To reduce the number of production steps by using a 1st transparent substrate with a 1st information recording face, a 1st reflecting film formed so as to cover the recording face and a 2nd reflecting film having a letter and/or graphic shape formed on a 2nd transparent substrate and disposing a transparent adhesive layer, which sticks the 1st and 2nd transparent substrates together with the 1st reflection film inward. SOLUTION: A 1st transparent substrate 101 is obtained by molding a resin material, such as polycarbonate resin or acrylic resin and has an information recording region 102 in which information is recorded as a sequence of pits on one face. A 2nd transparent substrate 105 has no the information recording region, both sides are specular surfaces, and a 2nd reflecting film 106, having a letter and/or graphic shape which expresses the information having relation with the information recorded in the information recording face of the 1st transparent substrate 101, is formed on one side. The 1st and 2nd substrates 101, 105 are stuck together by way of a transparent adhesive layer 104, in such a way that the 1st and 2nd reflecting films 103, 106 face opposite each other and a display comparable to a pit art is obtained.
