ABSTRACT:
A magnetic recording medium is disclosed, comprising a nonmagnetic support having thereon a lower nonmagnetic layer comprising nonmagnetic particles dispersed in a binder and further having on the lower layer an upper magnetic layer comprising ferromagnetic metal particles comprising alpha iron crystals dispersed in a binder, wherein said upper magnetic layer has diffraction dots attributable to the ferromagnetic metal particles present on the magnetic layer surface when analyzed by reflection high-energy electron diffraction, the number of said diffraction dots is from 5 to 15 when counted in a 100.degree. range on a circular arc of diffraction dots caused by diffraction on a (211) plane of said ferromagnetic metal particles present on the magnetic layer surface.
