| abstract | (57) [Abstract] [Purpose] To provide a magnetic recording medium capable of achieving both excellent electromagnetic conversion characteristics and high reliability, which are contradictory characteristics, even with a thin magnetic layer having a thickness of 0.3 μm or less. . [Structure] A single magnetic layer containing acicular ferromagnetic magnetic powder and a magnetic abrasive and having a thickness of 0.3 μm or less is provided on a non-magnetic support. The magnetic abrasive has an average particle size of 0.3 μm Hereinafter, the Mohs hardness is 5 or more, the coercive force Hc is 0.8 to 1.2 times the coercive force Hc of the needle-like ferromagnetic magnetic powder, and the shape is Any one of a spherical shape, a cubic shape, a prismatic shape, and a hexagonal prismatic shape is used. The magnetic layer has a coercive force Hc of 140 k. A / m or more and a saturation magnetic flux density Bm of 350 mT or more. |
