摘要：
Provided herein is an optical disc having: an optical plotting layer which is formed at a label surface side and on which an image is formed by heat change with a laser beam emitted from a recording surface side; a protective layer which is formed at the label surface side of the optical plotting layer, protects the optical plotting layer, and through which the image can be viewed from the label surface side; a reflective layer which is formed at the recording surface side of the optical plotting layer and reflects the laser beam; and a substrate which supports the reflective layer, the protective layer and the optical plotting layer.
