PROBLEM TO BE SOLVED: To make possible obtaining an inexpensive translucent reflection film easy to manufacture with reflectance and transmissivity of prescribed values or above by making the reflection film forming a first recording layer a film consisting of dystuff. SOLUTION: This optical information recording medium is provided with a translucent substrate 1, the first recording layer 2 consisting of the translucent reflection film placed on the substrate 1 and a second recording layer 4 consisting of the reflection film placed on the first recording layer 2, and the reflection film of the first recording layer 2 consists of the dystuff. Then, since the translucent reflection film forming the first recording layer 2 is the film consisting of the dystuff, the matter that the reflectance and transmissivity are made prescribed values or above also is easy, and the inexpensive manufacture is easy also. |
