    摘要: A mask forming method forms an A mask forming functional layer with an amorphous structure so as to cover an etched body, forms a B mask forming functional layer so as to cover the formed A mask forming functional layer, forms a convex/concave pattern in the formed B mask forming functional layer by carrying out a predetermined process to form a B mask on the A mask forming functional layer, and forms an A mask on the etched body by forming a convex/concave pattern in the A mask forming functional layer by dry etching the A mask forming functional layer using the B mask. By doing so, a convex/concave pattern with extremely small pattern fluctuations can be formed in the A mask forming functional layer.

    摘要: A method for forming a concavo-convex pattern that can form a fine and complex concavo-convex pattern such as that corresponding to servo information with high precision, a method for manufacturing a master disk, a method for manufacturing a stamper, and a method for manufacturing a magnetic recording medium using that method for forming a concavo-convex pattern are provided. A resin layer formed over a resin layer supporting member is processed into an irregular concavo-convex pattern in which a dividing convex portion is formed in a part of concave portions of a predetermined basic concavo-convex pattern and at least some of concave portions are divided as compared with corresponding concave portions of the basic concavo-convex pattern. A recording layer (the resin layer supporting member) is etched based on the resin layer to be processed into a concavo-convex pattern obtained by bringing the irregular concavo-convex pattern close to the basic concavo-convex pattern.

Such a stamper can be manufactured by the method comprising the steps of forming a convex-concave pattern on a substrate, forming, on the convex-concave pattern, a layer of a material 110 with no crystalline peak in X-ray diffraction, and removing the layer of the material with no crystalline peak in X-ray diffraction from said substrate and convex-concave pattern in intimate contact with the layer.

    摘要: A method for manufacturing a magnetic recording medium that has a sufficiently flat surface and includes a recording layer having a concavo-convex pattern that provides favorable accuracy of recording and reproduction. The manufacturing method includes the steps of: forming a lower non-magnetic film over a recording layer having a concavo-convex pattern; and forming an upper non-magnetic film on the lower non-magnetic film to fill concave portions 34 of the concavo-convex pattern. A bias power is applied to an object to be processed at least in the step of forming the upper non-magnetic film, and no bias power or a smaller bias power than the bias power applied in the step of forming the upper non-magnetic film is applied in the formation of the lower non-magnetic film.
