A magnetic recording medium of the present invention comprises: a substrate; a magnetic film formed on this substrate; and a nonmagnetic reinforcing agent mixed into the magnetic film and projected from the surface of the magnetic film. Assuming that the minimum flying height of the magnetic head which is lifted up over the magnetic film is h, a projection height T of the nonmagnetic reinforcing agent from the surface of the magnetic film satisfies the relation of h/4<T<h. By virtue of this, even if an amount of mixture of the nonmagnetic reinforcing agent which becomes a cause of the generation of the noises is reduced, the necessary durability can be obtained. |
