Abstract
A high-density reproduction-only optical disc includes a high frequency data zone in which disc related information is recorded by high frequency wobbles, a user data area in which user data is recorded by pits, and a transition zone which is formed between the high frequency data zone and the user data. Accordingly, the reliability of reproducing data from the user data area is improved.
