Abstract
A recording medium is disclosed. In the recording medium, address information is recorded in advance, one bit of the address information recorded is represented by a modulated wobble signal obtained by modulating each of a predetermined number of modulation unit sections of a wobble waveform, and a groove is formed in association with the modulated wobble signal, wherein, in converting the one bit of the address information into a chip sequence in which a predetermined number of chips continue, the modulated wobble signal is adapted such that a code sequence is inverted when the one bit is a first value and is not inverted when the one bit is a second value, and the modulated wobble signal is generated by modulating a wobble waveform in a modulation unit section according to a value of each of the chips of the chip sequence.
