場合に次のような問題が発生する。 The stamper 1 used for disk molding is obtained by processing a nickel electroformed plate onto which the surface of a master master is electroformed into a predetermined size.
However, the back surface 1a of this nickel electroformed plate, that is, the stamper 1, is the opposite surface to the transfer surface 1b, and although it is obtained in a matte state as a result of electroforming, it cannot be used for molding as it is because of the unevenness. It is used after polishing. However, this back side 1a
It is difficult to polish to a perfect mirror surface. So stamper side mold 3 and stamper 1
When installed, the mold surface 3a and stamper surface 1b
It is not possible to maintain full face contact with. Therefore, when disk molding pressure in directions A and A is applied between the stamper side mold 3 and the disk 2 side mold 4, the following problem occurs.

ツキ又は無電解メツキ等がある。 Next, one embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 2a is a plan view of the present invention, and FIG. 2b is a perspective view including a partial sectional view of the same. FIG. 3 is a sectional view showing an embodiment of the present invention corresponding to the main part of FIG. 1 (conventional example). The same reference numerals are used for the same parts as in the conventional structure, and explanations are omitted, but the difference between the present invention and the conventional example is that a film 5 of metal or alloy is formed on the back surface 1a of the stamper 1. It is. As a result, the satin-finished surface is the mold surface 3.
The film 5 acts as a medium between the film 5 and the film 5, and complete surface contact can be obtained by maintaining a familiar state through deformation of the film. Here, the membrane 5 can obtain the desired effect when molding pressure is applied by filling the void created between the back surface 1a of the stamper and the mold surface 3a.
A suitable thickness is about 1 to 2 times the surface roughness, that is, the depth of the unevenness. If it is too thick, it may cause harmful side effects due to distortion of the film. The depth of the surface unevenness is D in FIG. 4, which is the maximum depth of the surface unevenness, D to 2D is the film thickness, and 2D is the maximum film thickness. In view of the purpose and function of the present invention as described above, the most suitable material for the membrane 5 is a metal or alloy with high malleability and ductility, such as Au, Zn, Al, Cd, Sn, and Pb. Furthermore, as a method for forming the film, there are vapor deposition sputtering, electroplating, electroless plating, and the like.
