<P>PROBLEM TO BE SOLVED: To provide a disk structure whereby an information recording optical disk being an optical disk such as a card type optical disk atypical of a disk type optical disk and formed with a visible image at areas at the outside of data recording areas can simply be produced, and to provide the optical disk produced by the structure, an optical disk recording method to form the visible image on the areas of the optical disk, and an optical disk recording apparatus. <P>SOLUTION: Employing the disk type optical disk having one perforated line or more to obtain an optical disk atypical of the disk type optical disk by cutting off a slice at the perforated line forms a visible image at the outside of an inscribed circle with a part of the optical disk atypical of the disk type optical disk. A user cuts off the slice at the perforated line of the disk type optical disk to obtain the atypical optical disk on data recording disabled areas of which on a recording face the visible image is formed. <P>COPYRIGHT: (C)2004,JPO |
