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 adjaceritiy 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). An expression, 100 nm < T1 < 200 nm, is satisfied, where T1 represents an amount of protrusion of said first curved portion (44) with respect to said first groove (42a).
