<p>An optical disc is provided, which includes a substrate having micro-embossments, in which flat portions (600) and track guides (500) protruded from the surfaces of the flat portions (600) are provided, a reflective layer (401) formed on the substrate (405), a dielectric layer (402) formed on the reflective layer (401), a recording layer (403) formed on the dielectric layer (402), and a protective layer (404) formed on the recording layer (403). Thus, the lands (600) and hills (500) on the substrate (405) of the optical disc enable disc fabrication to be facilitated. Accordingly, tracks of the disc can be narrowed, to thereby enhance a recording density. <IMAGE></p> |
