<P>PROBLEM TO BE SOLVED: To provide an optical disk and an image forming method, with which formation of an image of a chromatic color by laser light is easily carried out. <P>SOLUTION: The optical disk has a color layer formed on the principal surface of a substrate and an opaque coating layer which is formed on the color layer and is removed or made transparent by irradiation of laser light. Laser light is condensed on the coating layer and is made to scan to remove the coating layer or make the coating layer transparent, and thus the color layer is made to appear to form an image. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
