The invention provides a nanostructure including an anodized film including nanoholes. The anodized film is formed on a substrate having a surface including at least one material selected from the group consisting of semiconductors, noble metals, Mn, Fe, Co, Ni, Cu and carbon. The nanoholes are cut completely through the anodized film from the surface of the anodized film to the surface of the substrate. The nanoholes have a first diameter at the surface of the anodized film and a second diameter at the surface of the substrate. The nanoholes are characterized in that either a constriction exists at a location between the surface of the anodized film and the surface of the substrate, or the second diameter is greater than the first diameter.

摘要:
A magnetic recording medium includes a cylindrical substrate and pores embedded with a magnetic substance that are provided on the outer circumferential surface of the cylindrical substrate and aligned in tracks that are in parallel with one another along the center axis of the cylindrical substrate. The tracks have as their center the center axis of the cylindrical substrate, and form circular orbits defined by planes perpendicular to the center axis. Alternatively, the tracks are in a spiral orbit or in spiral orbits whose center is the center axis of the cylindrical substrate. The pores at intersections of vertical and horizontal rows are aligned in quadrilaterals such as squares, rectangles or rhombi.

A method of producing a structure having narrow pores includes a first step of bringing pore-guiding members into contact with upper and lower surfaces of a member comprising aluminum as a principal ingredient and a second step of anodizing the member comprising aluminum as the principal ingredient to form narrow pores. The pore-guiding members contain the same material as a principal ingredient. The second step includes preferably a step of transforming the member comprising aluminum as the principal ingredient into a porous body comprising alumina having narrow pores oriented substantially parallel to the interfaces between the pore-guiding members and the member comprising aluminum as the principal ingredient.
