PROBLEM TO BE SOLVED: To provide a magnetic recording medium having a good noise characteristic, and the difficulty of the occurrence of thermal fluctuation phenomenon, and to provide its manufacturing method and a magnetic recording/reproducing device. SOLUTION: On a nonmagnetic substrate 1, a soft magnetic substrate film 2 made of a soft magnetic material, an orientation control film 3 for controlling the orientation of a film directly above, a perpendicular magnetic film 4 having a magnetization facilitation axis oriented perpendicularly to the substrate, and a protective film 5 are provided. The orientation control film 3 is provided with a second orientation control layer 3b made in an hcp structure on the first orientation control layer 3a of a B2 structure. The thickness of the first orientation control layer 3a is set in the range of 0.1 to 20 nm, and the thickness of the second orientation control layer is set in the range of 0.1 to 50 nm.
