A magnetic recording medium comprising a substrate and a magnetic layer provided thereon, the magnetic layer containing: a binder, (a) an acicular ferromagnetic metal powder having an average major axis length of 0.05 to 0.14 mu m and a coercive force of 1700 to 2300 Oe or (c) a tabular hexagonal ferrite powder having a tabular diameter of 0.01 to 0.07 mu m and a coercive force of 1400 to 2200 Oe, and (b) a spherical or amorphous spinel ferrite powder having an average particle size of 0.005 to 0.09 mu m and a coercive force of more than 0 and less than 150 Oe, wherein the mixing ratio of the spinel ferrite powder (b) to the ferromagnetic metal powder (a) or the hexagonal ferrite powder (c), i.e., (b)/(a) or (b)/(c), is 0.03 to 0.3 by weight. |
