PROBLEM TO BE SOLVED: To provide a magnetic recording medium which does not require high-temperature processing for exhibiting magnetization of nano particles and is superior in flatness of a nanoparticle film, and its manufacturing method and apparatus. SOLUTION: In the medium, a substrate has a nanoparticle layer composed of nano particles, having an average particle diameter of≥1 nm and≤20 nm and containing at least one kind of element among Fe, Co, Ni, Mn, Sm, Pt and Pd and an organic compound imposing among alignments of the nano particles, infrared lights are irradiated on to the nanoparticle layer of the substrate to exhibit the magnetization, the directions of axes of easy magnetization of the magnetized nano particles are aligned approximately one directions by applying a magnetic field to the nanoparticle layer, the organic compound is fixed to the nanoparticle layer by irradiating ultraviolet lights, and the axis of the easy magnetization are aligned approximately in parallel with a specific direction to the substrate. Accordingly, the medium which not produce deterioration in a base film and a soft magnetic film, but will exhibit proper magnetic characteristics can be provided. COPYRIGHT: (C)2004,JPO&NCIPI |
