<P>PROBLEM TO BE SOLVED: To provide an optical disk drive for forming a visible image in a plurality of colors on a disk without the need for individually preparing a new drive or the like. <P>SOLUTION: Color development layers for starting color development through reception of different energies such as a blue color development layer 205, a green color development layer 206, and a red color development layer 207 are stacked on an image side of an optical disk D. A laser beam is emitted to the color development layer sequentially in the order of layers with a smaller energy required for color development and an ultraviolet ray is emitted to the color development layers to fix the color of the color development layers after that. Then the laser beam with a required power is emitted to a succeeding color development layer to fix the layer and a laser beam required is emitted to the final color development layer to develop the color. <P>COPYRIGHT: (C)2003,JPO |
