A method for producing a multilayer optical disk including a plurality of information storage layers is disclosed. The method includes a mastering step of preparing a plurality of metal dies, a replicating step of producing a base plate onto which a desired pattern is transferred using the plurality of metal dies and forming recordable/reproducible information storage layers. The desired pattern includes a wobbling tract pattern that is formed by combining a plurality of wobble patterns each having the same fundamental frequency. The mastering step produces the plurality of metal dies for the plurality of information storage layers having a shape that specifies a track groove whose shape factor differs from one information storage layer to another.
