ABSTRACT:
In an optical disk of a single-spiral configuration, and including a first sequence of address pits and a second sequence of address pits, wherein headers include first and second sequences of address pits provided in different positions along the track. The first sequence of address pits are shifted by half a track pitch in a first radial direction so that its center line is aligned with a first boundary between a land track and a groove track following the header. The second sequence of address pits are shifted in a second radial direction opposite to the first radial direction by half a track pitch so that its center line is aligned with a second boundary (next to the first boundary) between a land track and a groove track following the header. The first sequence of address pits indicate an address of a sector in a first one of a land track and a groove track following the header. The second sequence of address pits indicate an address of a sector in a second one of a land track and a groove track following the header. The disk may further comprises mirror surface parts provided following the first and second sequences of address pits in a header at the connecting point. The offset in the tracking error signal is detected when the light spot is scanning the sequences of address pits and/or the mirror surface parts.
