摘要： An imprinting method which is capable of forming a concave/convex pattern in a short time without causing deformation or incompleteness of the pattern. In the imprinting method, a stamper-pressing step of pressing a stamper against a resin layer formed by applying a resin material to a surface of a substrate, in a state of the resin layer being heated to a predetermined temperature, and a stamper-removing step of removing the stamper from the resin layer while maintaining either of the state of the resin layer being heated and a state of the temperature of the heated resin layer being held, are performed in the mentioned order, whereby shapes of recesses/protrusions of the stamper are transferred to the resin layer to form a concave/convex pattern on the substrate.

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 magnetic recording medium is provided, which has a recording layer formed in a concavo-convex pattern and makes it possible to obtain the stable flying characteristics of a head. In the magnetic recording medium, concave portions between recording elements are filled with a non-magnetic material. Thus, the surface of the magnetic recording medium takes a concavo-convex shape which is different from the concavo-convex pattern of the recording layer. Also, the arithmetical mean deviation of the assessed profile of the concavo-convex shape in the surface is restricted to 1 nm or less.

摘要： A mold having a pattern of a concavo-convex surface including protrusion and recess is prepared and the pattern is transferred to a resist layer formed on a substrate by an imprinting method. The side surface of a protrusion of the transferred resist pattern is then etched so that the protrusion has a width narrower than a width of the corresponding recess formed to the mold. This resist pattern forming method is preferably applicable to a magnetic recording medium manufacturing method and a magnetic head manufacturing method.

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.
