PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording medium and a magnetic storage device in which magnetic properties of respective ferromagnetic layers can be controlled and thermal stability of residual magnetization is good in a perpendicular magnetic recording medium having recoding layers comprising of a plurality of magnetic layers. SOLUTION: The device is constituted of a substrate 11 and has a soft magnetic back lining laminated body 12, a seed layer 13, an intermediate layer 14, a recording layer 15, a protection layer 19, and lubrication layer 20, laminated on the substrate 11 in order, wherein the recording layer 15 has a first magnetic layer 16, a growth intercepting layer 17 and a second magnetic layer 18, laminated in this order from the intermediate layer 14 side, and the growth intercepting layer 17 comprises of amorphous ferromagnetic material. Since the growth intercepting layer 17 is amorphous, the second magnetic layer 18 is crystal-grown without being affected by crystal structure of the first magnetic layer 16 and particle diameter of the first magnetic layer 16. Also, since the growth intercepting layer 17 is the ferromagnetic material, the first magnetic layer 16 and the second magnetic layer 18 are coupled in a ferromagnetic state.
