PROBLEM TO BE SOLVED: To provide a magnetic recording medium in which magnetic particles in a magnetic layer are hard to form an aggregate, are excellent in productivity, and exhibit ferromagnetism. SOLUTION: The magnetic recording medium is prepared by setting up magnetic layers which contain magnetic particles having ferromagnetic ordered alloy phases on a support object. After producing alloy particles which can form a CuAu type or Cu<SB>3</SB>Au type ferromagnetic ordered alloy phase, the above magnetic layer is formed by annealing the above alloy particles in the state of contained in a solvent to make magnetic particles, and applying an application liquid containing the magnetic particles, binders, polar solvents, and nonpolar solvents concerned on the support object. Also, the magnetic recording medium is prepared by setting up the magnetic layer containing the magnetic particles having ferromagnetic ordered alloy phases on the support object. Further, the magnetic recording medium contains the binder, the polar solvent, organic substances and the nonpolar solvent in the magnetic layer. COPYRIGHT: (C)2005,JPO&NCIPI |
