description An optical disc includes a plurality of lands and grooves alternately arranged in a radial direction of the optical disc, each land wobbling in the radial direction and recording a header recording part for holding address information, there being a difference in elevation between each land and each groove, each grove having a data recording part for storing data, wherein the header recording parts offset alternately for respective lands in the radial direction, the data recording part in the groove and the header recording part in the land are arranged offset in a circumferential direction of the optical disc, and the header recording part in each land enables the same address information to be reproduced for two groove at both sides of each land.
