Abstract: An optical disk (10A) includes a substrate (18) comprising a recording layer (28) and a pregroove (16), which are formed in this order as viewed in a direction in which a recording and/or reproducing laser beam (32) is radiated, wherein the pregroove (16) includes a plurality of meandering portions (40). Each of the meandering portions (40) includes a first curved portion (44), which is curved toward a first groove (42a) disposed adjacently on one side of a land (36), and a second curved portion (46), which is curved toward the land (36) from a second groove (42b) disposed adjacently on the other side of the land (36).
