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.
Claims37
A high-density reproduction-only optical disc comprising:
- 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 data pits;
- and
- a transition zone which is formed between the high frequency data zone and the user data area.
A method of reproducing data from a reproduction-only optical disc having a data zone, a user data area, and a transition zone, the method comprising:
- reproducing disc related information recorded by wobbles in the data zone using a push-pull channel;
- reproducing user data recorded by data pits in the user data area using a sum channel;
- and
- reproducing transition-zone information from the transition zone formed between the data zone and the user data area, using both the push-pull channel and the sum channel.
A reproduction-only medium comprising:
- a data zone in which disc related information is recorded by wobbles;
- a user data area in which user data is recorded by data pits;
- and
- a transition zone which is formed between the data zone and the user data area.
A method of recording data with respect to a reproduction-only optical disc having a data zone, a user data area, and a transition zone, the method comprising:
- recording disc related information by wobbles in the data zone;
- recording user data by data pits in the user data area;
- and
- recording transition-zone information in the transition zone formed between the data zone and the user data area.
