Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image-recording method for an optical disk, which is capable of forming an image at high speed by using laser light while keeping high resolution capability. SOLUTION: In the image-recording method for an optical disk, an image is formed by irradiating an image recording layer formed on a substrate with laser light. In addition, the maximum length in the radius direction of the spot shape of the laser light is longer than that in the circumference direction. COPYRIGHT: (C)2006,JPO&NCIPI
