| 摘要 |
An aspect of the present invention relates to a magnetic recording medium comprising a nonmagnetic layer containing a nonmagnetic powder and a binder and a magnetic layer containing a ferromagnetic powder and a binder in this order on a nonmagnetic support, wherein the magnetic layer comprises a nonmagnetic powder of which coefficient of variation CV of a particle size distribution as denoted by the following formula (1): CV(%)=σ/φ×100 (1) is less than 20 percent, and the magnetic layer has a thickness being equal to or less than 0.1μm and falling within a range of 1.1≰φ/t≰8.0, whereinσdenotes a standard deviation of a particle diameter,φdenotes an average particle diameter of the nonmagnetic powder comprised in the magnetic layer being expressed inμm, and t denotes a thickness of the magnetic layer being expressed inμm.
