PROBLEM TO BE SOLVED: To provide a magnetic recording medium having excellent thermal stability of written bits, low medium noise characteristics and satisfactory writing performance and to provide a magnetic storage device. SOLUTION: The magnetic recording medium 10 has a substrate 11, and on the substrate 11, a first seed layer 12, a second seed layer 13, an under layer 14, a non-magnetic intermediate layer 15, a first ferromagnetic layer 16, a first non-magnetic coupling layer 18, a second ferromagnetic layer 19, a second non-magnetic coupling layer 20, a magnetic layer 21, a protective layer 22 and a lubricant layer 23 sequentially formed. The second ferromagnetic layer 19 and the magnetic layer 21 are antiferromagnetically exchange coupled via the second non-magnetic coupling layer 20, the first ferromagnetic layer 16 and the second ferromagnetic layer 19 are ferromagnetically exchange coupled via the first non-magnetic coupling layer 18, and a relationship of Hc<SB>1</SB>'<Hc<SB>3</SB>'≤Hc<SB>2</SB>' is satisfied.
