Claims
- 1. A method of producing an optical information record carrier comprising the steps of:
- forming a first reflecting layer made of silicon on a surface of a transparent substrate having a predetermined first pit pattern on said surface such that said first reflecting layer has said pit pattern;
- holding a transparent stamper, having a radiation transmitting property and having a predetermined second pit pattern on a surface thereof, such that said surface of said stamper covers said first reflecting layer with a liquid radiation setting resin disposed therebetween;
- irradiating said radiation setting resin with radiation from said transparent stamper side;
- peeling said transparent stamper from the radiation setting resin layer after said radiation setting resin has hardened;
- forming a second reflecting layer made of aluminum on said hardened radiation-setting resin layer such that said second reflecting layer has said second pit pattern; and
- laminating a protective layer on said second reflecting layer for protecting said second reflecting layer.
- 2. The method according to claim 1, wherein said first and second reflecting layers are made of multi-layer dielectric films.
- 3. The method according to claim 1, characterized in that said transparent stamper is made of glass or plastics having radiation transmitting property.
- 4. A method of producing an optical information record carrier comprising the steps of:
- forming a first reflecting layer made of silicon and having a first reflection light band on a transparent substrate;
- holding a stamper on said first reflecting layer with a liquid radiation setting resin disposed therebetween;
- irradiating said radiation setting resin with radiation through said first reflecting layer to thereby harden said radiation setting resin so as to form a transparent layer; and
- forming a second reflecting layer made of aluminum on said transparent layer, said second reflecting layer having a second reflection light band which is different from said first reflection light band, wherein each of said reflecting layers and said transparent layer has fine recess and protrusion portions.
- 5. A method of producing an optical information record carrier according to claim 4, characterized in that each of said first and second reflecting layers is constituted by a dielectric multi-layer film.
