Optical information recording medium and optical information recording medium reproducing device

An optical information reproducing device configured to optically reproduce an optical information on recording medium of a constant angular velocity (CAV) or a zone CAV comprising:

• a groove which continuously wobbles and is preliminarily formed, and a land adjacent to the groove, wherein information is recorded in the groove and the land,
• wherein the groove has a first wobble part which is modulated by groove address information of the groove, a second wobble part which is modulated by address information of the land adjacent to the groove and a third wobble part which is modulated by address information of another land adjacent to the groove,
• a first section sandwiched between the second wobble parts of two adjacent grooves and a second section sandwiched between the third wobble parts of the two adjacent grooves are formed on the land,
• one of phases of wobbles on both sides of the first section and phases of wobbles on both sides of the second section are substantially in-phase, and
• the optical information reproducing device is configured to reproduce the address information of the land, when the land is scanned, from one of the first section and the second section in which the phases of the wobbles are substantially in-phase.
