A stamper which has a region information according to a destination is set to the resin molding machine for HDDVD and the resin molding machine for DVD, respectively. The contents information (contents A) of the same program is held in each stamper. The region information of each stamper is different according to the destination of contents information. Two disc substrates to which the information on each stamper is transferred are formed using the resin molding machine for HDDVD and the resin molding machine for DVD, and the reflecting layer is further formed on the transfer face of each substrate by sputtering. And as the reflecting layer side faces each other, each disc substrate is laminated. Thereby, hybrid type next-generation DVD from which the destination of the contents information of a HDDVD layer and a DVD layer is different is manufactured.
