(57) [Abstract] [Purpose] To provide a magnetic recording medium capable of high density recording and excellent in electromagnetic conversion characteristics and durability. In a magnetic recording medium comprising a flexible support, an underlayer formed on the support, and a magnetic layer formed on the underlayer, the underlayer comprises a binder and average particles. The nonmagnetic particles having a diameter of 0.01 to 0.20 μm, the content of the nonmagnetic particles in the underlayer is 40 to 85 wt%, and the magnetic layer is composed of a ferromagnetic powder, a binder, and an average particle. It contains an abrasive having a diameter of 0.10 to 0.40 μm, the thickness of the magnetic layer is 0.10 to 0.30 μm, and the abrasive is 1 to 5 with respect to 100 parts by weight of the ferromagnetic powder. It is configured so that it is contained by weight. |
