摘要：
Provided herein is an optical disc having: an optical plotting layer 17 which is formed at a label surface B-side and on which an image is formed by heat change with a laser beam 28 emitted from a recording surface A-side; a protective layer 18 which is formed at the label surface B-side of the optical plotting layer 17, protects the optical plotting layer 17, and through which the image can be viewed from the label surface B-side; a substrate 15 which supports the protective layer 18 and the optical plotting layer 17; and a guide track 24 which is formed on the optical plotting layer 17 so as to be intermittent in a guide direction.
