Zusammenfassung:	PROBLEM TO BE SOLVED: To improve durability of a magnetic recording medium and magnetic parametric performance. SOLUTION: A layer comparatively rich in abrasive agent is formed on a surface layer of a magnetic layer 2 and an area rich in a magnetic ingredient is formed deeper than 50 [ ] below the surface of the magnetic layer 2 in the magnetic recording medium 10 which has the magnetic layer 2 formed by coating of a magnetic paint on a nonmagnetic support medium 1.
