ABSTRACT:
Two or three different signal recording regions are formed in one optical disk. One signal recording region is positioned at a depth of 0.6 mm from a disk surface and is formatted in accordance with a single layer or two layer DVD standard, for example. Remaining signal recording region is positioned at a depth of 1.2 mm from the disk surface and is formatted in accordance with the CD, CD-R or MO disk standard, for example. By using such an optical disk, whether a manufactured optical pickup device is capable of reproducing two or three different types of optical disks can be checked quickly.
