Abstract:
According to an embodiment, the invention is directed to an optical disc having signal tracks including a groove track, in which wobble signals are recorded on at least the groove track. Wobble units of wobble signals are modulated on the groove track, while at least 4 wobble units are used to represent a data bit of “0” or “1” in address information. Data bit of “0” or “1” in address information has a same phase and different phase with regard to alternate data bit at least to distinguish from each other.
