Magnetic recording medium |
| abstract |
Disclosed is a magnetic recording medium having a flexible nonmagnetic support, a nonmagnetic layer containing a nonmagnetic powder and a binder on the support, and a magnetic layer containing a ferromagnetic powder and a binder. The magnetic layer has an average thickness d of 0.01 to 0.3 mum, a ratio sigma/d of a standard deviation sigma in the thickness of the magnetic layer to the average thickness d equal to or less than 0.5, and, according to the roughness spectrum of a magnetic layer surface measured with an atomic force microscope, a PSD of 0.5 nm2 or lower in a wavelength of 1 to 5 mum and a PSD of 0.02 to 0.5 nm2 in a wavelength of 0.5 mum or more to less than 1 mum. |
