PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording medium having excellent low noise characteristics and stability of recording magnetization and suitable for super high density magnetic recording and to provide a magnetic storage device. SOLUTION: In the perpendicular magnetic recording medium, a perpendicularly magnetized film 20 having a laminated structure consisting of Co/(Pt or Pd) multilayered films 14, 16 and 18 and Co-Xa/(Pt or Pd) multilayered films 15 and 17 (Xa: Cr, B, Ta, Mn, V) or consisting of the Co/(Pt or Pd) multilayered films and Co/(Pt-Ya or Pd-Ya) multilayered films (Ya: B, Ta, Ru, Re, Ir, Mn, Mg, Zr, Nb) is used and an amorphous material or a polycrystalline thin film having a noncolumnar structure is used as a backing layer 12 whose magnetic domain structure is controlled by a magnetic domain fixing layer.
