| abstract | (57) [Abstract] [PROBLEMS] A magnetic recording medium having a high C / N ratio in a high frequency region and having characteristics particularly suitable for a digital recording medium. [Structure] A plurality of layers including a non-magnetic layer and a magnetic layer are provided on a support, and the ferromagnetic powder (A) contained in the magnetic layer contains 2 to 20 parts by weight of Al and 100 parts by weight of Fe atoms, and Co. 1 0 to 60 parts by weight and 1 to 16 parts by weight of at least one rare earth element selected from Sm, Y, Pr, Nd and La, and its saturation magnetization (σs) is 130 to 170e. mu / g, the average major axis length of the ferromagnetic powder (A) is La (nm), the axial ratio is Xa, and the average major axis length of the nonmagnetic powder (B) contained in the nonmagnetic layer is Lb ( nm), the axial ratio is X When b, 30 ≦ La ≦ 110 3 ≦ Xa ≦ 8 La <L b 80 ≦ Lb ≦ 280 5 ≦ Xb ≦ 12, and the average surface roughness (Ra) of the uppermost magnetic layer is 0.0005 to 0.006 μm. |
