<P>PROBLEM TO BE SOLVED: To provide an optical disk which can have a visible image of high visibility recorded in an image recording layer on its label surface side by using laser light. <P>SOLUTION: The optical disk has, on the label surface side, the image recording layer where a visible light is recorded by irradiating it with the laser light, a resin layer with a refractive index of 1.4 to 1.6, and an antireflective layer with a refractive index of 1.2 to 1.4 as an outermost surface layer in this order. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
