<P>PROBLEM TO BE SOLVED: To provide an optical disk for reproducing an address signal, at high speed with high reliability. <P>SOLUTION: To provide a wobble addressing method for the optical disk, with a combined use of wobble of plural modulation and coding methods. Wobble information includes non-modulated wobbles. Consequently, synchronization with the address signal is facilitated, the address signal can be reproduced at a high speed. Because of an effective modulation method for the address signal and redundancy, address information can be detected with high reliability. <P>COPYRIGHT: (C)2009,JPO&INPIT |
