<P>PROBLEM TO BE SOLVED: To provide an optical disk having an image recording layer which can record a visible image on a label face using a laser beam. <P>SOLUTION: The optical disk is made by laminating; a 1st layered body having an information recording layer 20 or an information recording section and a 1st reflective layer 30 in this order on a 1st substrate 10; and a 2nd layered body having an image recording layer 80a on which a visible image is recorded by irradiation of a laser beam and a 2nd reflective layer 70 in this order on a 2nd substrate 90a in which a groove is prepared via an adhesive layer 50 so that both reflective layers may counter. Thicknesses of both the 1st reflective layer 30 and the 2nd reflective layer 70 are in the range of 15-200 nm and the image recording layer contain pigment. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
