Abstract: PURPOSE:To obtain the perpendicular magnetic recording medium which can eliminate cracks and spacing losses, has high reliability and high mass productivity and is excellent in electromagnetic conversion characteristics by using a nonmagnetic base having a specific Young's modulus, surface roughness and filler density. CONSTITUTION:A perpendicularly magnetized film of a Co-O system is formed on the nonmagnetic base having 600-1,300kg/mm<2> Young's modulus, 3-40Angstrom  surface roughness Ra and 50,000-500,000 pieces/mm<2> filler density. Since the Young's modulus of the nonmagnetic base is set in the prescribed range in such a manner, the elongation rate and deformation quantity to tension are suppressed. The stress that the perpendicularly magnetized film of the Co-O system receives is suppressed and the cracks are eliminated. Further, the surface condition (surface roughness and filler density) of the nonmagnetic base is specified and the spacing loss at the time of recording and reproduction is decreased. The high output in a short wavelength region is obtainable particularly in terms of electromagnetic conversion characteristics. The perpendicular magnetic recording medium having the excellent productivity and reliability and the excellent magnetic characteristics and electromagnetic conversion characteristics is thereby obtd.
