A magnetic recording medium has high corrosion resistance and high Bs, a method of manufacturing the magnetic recording medium, and a magnetic recording device. The magnetic recording medium using as a recording layer a magnetic layer has perpendicular magnetic anisotropy. A soft magnetic backing layer (upper and lower soft magnetic backing layers) formed under the recording layer is composed of a FeCoZr alloy added with at least one element of Ta and Nb and further added with Cr. This magnetic recording medium includes the soft magnetic backing layer having high corrosion resistance and high Bs and therefore, exhibits high Hc recording and high S/N performance.
