OPTICAL RECORDING OR REPRODUCING APPARATUS FOR DATA FROM AN OPTICAL DISC HAVING UNIFORM STRUCTURE |
摘要 |
An optical disc is manufactured under a uniform condition by forming grooves and lands on the entire surface of the disc. The optical disc is configured to obtain a reliable reproduction signal, and the grooves and lands are formed on a lead- in area, a user data area and a lead-out area of the optical disc. Since the same manufacturing condition can be adopted in mastering discs, the yield can be enhanced and the manufacturing cost can be reduced.
