ABSTRACT:
A first recording layer for recording information of an optical disk and a second recording layer of the optical disk on which a visible image can be recorded are disposed at an interval of 0.5 mm or more. Thus, even when a high power laser is used on one of the layers, data on the other layer will not be destroyed.
