PROBLEM TO BE SOLVED: To provide a magnetic recording medium capable of developing a high vertical coercive force by decreasing the magnetic coupling between magnetic particles. SOLUTION: The magnetic recording medium is characterized in to include a recording layer comprising a ferromagnetic body expressed in general formula: [(Co<SB>1-m</SB>Pt<SB>m</SB>)<SB>1-n</SB>Cr<SB>n</SB>]<SB>100-x-y</SB>Ta<SB>x</SB>O<SB>y</SB>, wherein m, n are atomic ratios, m is≥0.2 and≤0.4, n is≥0 and≤0.1, y is≥16 at.% and≤26 at.%, and y/x≥1.7 and≤2.3.
