Disclosed is a method for manufacturing a disc-shaped recording medium by use of a stamper member made of a high-cost resin material. This method involves applying an energy beam curing resin to a first recording layer formed on a disc-shaped substrate, disposing the stamper member so a first transfer face thereof faces the disc-shaped substrate and rotating the disc-shaped substrate in order to spin-coat resin between the disc-shaped substrate and the stamper member. The irradiating the energy beam curing resin with an energy beam while rotating the disc-shaped substrate, exfoliating the stamper member to leave, on the disc-shaped substrate, a first spacer layer, forming a second recording layer on the surface of the first spacer layer applying the energy beam curing resin to the second recording layer, disposing the stamper member so that its second transfer face opposite to the first transfer face thereof faces the disc-shaped substrate, similarly forming a second spacer layer on the second recording layer and forming a third recording layer on the surface of the second spacer layer transferred from the second transfer face. |
