    摘要: A magnetic recording medium comprising: a nonmagnetic support; and a magnetic layer comprising a binder and ferromagnetic powder dispersed in the binder, wherein the magnetic layer has a surface waviness of from 3 to 15%, the surface waviness being calculated by {[(a total of cross-sectional areas of the magnetic layer at a position 5 nm in an above direction from an average plane of surface waviness of the magnetic layer)+(a total of cross-sectional areas of the magnetic layer at a position 5 nm in a below direction from the average plane of surface waviness of the magnetic layer)] (μm2)/a area of a surface of the magnetic layer to be measured (μm2)}×100(%).
