METHOD OF MANUFACTURING SmCo-BASED MAGNETIC PARTICULATE AND METHOD OF MANUFACTURING MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method by which a magnetic recording medium achieving higher-density recording can be manufactured.;SOLUTION: The method of manufacturing SmCo-based particulates includes steps of: heating a reaction solution containing Sm salt, Co salt and an organic polymer and/or a ligand compound, and a reaction solvent in which they are dissolved to produce a solid mixture containing SmCo-based particulates and the organic polymer and/or ligand compound in the reaction solution; and removing some of the organic polymer and/or ligand compound from the solid mixture by dissolving them in the solvent to obtain SmCo-based particulates having the remaining organic polymer and/or ligand compound stuck.;COPYRIGHT: (C)2009,JPO&INPIT
