PROBLEM TO BE SOLVED: To provide a magnetic recording medium which has a soft magnetic backing layer with high corrosion resistance and high Bs (saturation magnetization intensity), has high corrosion resistance, achieves high Hc (coercive force) recording and has high S/N performance, to provide a method of manufacturing the magnetic recording medium and to provide a magnetic recording device. SOLUTION: The magnetic recording medium 10 has a magnetic layer showing perpendicular magnetic anisotropy as a recording layer 18 and a material of the soft magnetic backing layer (an upper soft magnetic backing layer 13c and a lower soft magnetic backing layer 13a) formed in a lower layer of the recording layer 18 is alloy formed by adding at least one element of Ta and Nb and further adding Cr to FeCoZr alloy. According to the magnetic recording medium 10 provided with the soft magnetic backing layer, the soft magnetic backing layer having high corrosion resistance and high Bs is formed and the magnetic recording medium achieving high Hc recording and having high S/N performance can be achieved.
