PROBLEM TO BE SOLVED: To provide an optical disk having a warp characteristic which is suitable for signal reproduction after an ultraviolet ray hardening resin is applied or two baseboards are adhered when the two baseboards are adhered and to provide a method for producing the optical disk, by which the optical disk is produced with a high yield. SOLUTION: The optical disk consists of first and second baseboards which are formed to be projected to the direction of adhering surfaces when the two baseboards are adhered by optical disk baseboard injection molding molds 40 and 50 having a curved surface on the front surface of a mold cavity. |
