PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic recording medium, in which the saturation of an MR head is avoided and has especially high S/N ratio, and medium noise and error rate are reduced, by improving interface fluctuations and the surface of the medium. SOLUTION: In the method of manufacturing the magnetic recording medium, an application liquid containing ferromagnetic powder and a binding agent for a magnetic layer is applied to the surface of a nonmagnetic layer to form a magnetic layer whose thickness is 25-150 nm, the nonmagnetic layer being formed by applying the application liquid containing a nonmagnetic powder and a binding agent for a nonmagnetic layer to the surface of a base material so that it is 0.5-2.5μm in thickness, 20-120 m<SP>2</SP>/ml (nonmagnetic layer) in specific surface area, 0.15-0.40 ml/ml in micropore volume (nonmagnetic layer) and 3-16 nm in average micropore radius.
