A reflective layer is formed covering the recorded area 3 and covering the display area forming a transparent display area at least in part of the display area. And to the transparent display area, a print layer is provided. According to this composition, there is provided the transparent display area without the reflective layer in the optical disk with a recorded area of a small diameter. Therefore, discrimination of the size or diameter of a record area of 12 cm CDs is made easier, and the print layer provided to the transparent display area can be seen from both sides of the optical disk.
