Abstract

PURPOSE:To form the magnetic recording medium having the stabilized magnetic characteristic by a method wherein at least one kind out of P, As, Sb, Bi is implanted to a magnetic substance layer, and after then, a heat treatment is performed. CONSTITUTION:A ferromagnetic substance metal mainly consisting of Co is adhered aslant according to the vacuum evaporation method, the ion plating method, the sputtering method, etc., on the surface of a substrate consisting of a macromolecular film of polyester, etc., to form the magnetic substance layer. After the magnetic substance layer is formed on the substrate, at least one kind out of P, As, Sb, Bi is implanted to the magnetic substance layer from an ion source. After ion implantation is implemented, the heat treatment is performed to the substrate at the degree of 400-900 deg.C. When the heat treatment is performed to the magnetic substance layer implanted with P, etc., migration of P, etc., is generated. Namely, it is well-known by now that the magnetization characteristic of the magnetic substance layer according to Co-P, etc., is favorable, while the implanting quantity of P, etc., can be controlled easily according to this invention, and because migration of P, etc., can be attained according to the subsequent heat treatment, the magnetic recording medium having the favorable magnetization characteristic can be obtained easily.
