Method of reproducing data with respect to an optical disc, optical disc and appartus for reproducing data from an optical disc

摘要

A method of transferring data with respect to an optical storage medium comprising a lead-in area, which comprises a read only area and a readable/recordable area, and a user data area in which user data is recorded, the method comprising:
transferring first data with respect to a first wobble formed in the read only area of the lead-in area;
transferring second data with respect to the readable/recordable area, in which a second wobble is formed, of the lead-in area;
wherein the first wobble is modulated by a first modulation method and the second wobble is modulated by second modulation method different to the first modulation method.
