摘要： A magnetic recording medium comprises a non-magnetic base material; a lower magnetic layer containing a magnetic powder for recording in a long wavelength range and a resin binder; an upper magnetic layer containing a magnetic powder for recording in a short wavelength range and a resin binder; and an intermediate layer disposed between the two magnetic layers. By properly selecting the type and amount of resin binder contained in the upper magnetic layer and by disposing the intermediate layer whose main component is a resin binder, dispersion property of the magnetic powder in the upper magnetic layer can highly be improved, and thin and smooth magnetic layers can be obtained. Thus, the recording medium provides excellent reproduction characteristics in the wide wavelength range and has excellent running durability. In particular, the reproduction characteristics in a short wavelength range can be improved. A hexagonal ferrite powder is suitably used as the magnetic powder for recording in the short wavelength range. As the resin binder for the intermediate layer, a polyisocyanate compound whose molecular weight is 1,000 or less is particularly effective.

摘要： A magnetic recording medium comprises a non-magnetic base material, a lower magnetic layer containing a magnetic powder for recording in a long wavelength range, and an upper magnetic layer containing a magnetic powder for recording in a short wavelength range. By adding a small particle abrasive with a median diameter in the range from 0.05 to 0.3 .mu.m to the upper magnetic layer and by properly selecting the type and amount of a resin binder contained in the upper magnetic layer, a satisfactory abrasion effect can be obtained. This effect can be obtained, even if the abrasive with a small particle diameter is used without necessity of increase of the amount thereof. In addition, by using this abrasive, even if the upper magnetic layer is thin, the surfaces of the upper magnetic layer and the lower magnetic layer can be smoothened. Therefore, an excellent magnetic recording medium having high recording and reproduction characteristics in a wide wavelength range and high running durability can be provided. In particular, the recording and reproduction characteristics in a short wavelength range can be improved. A hexagonal ferrite powder can be used as a magnetic powder for recording in a short wavelength range.

摘要： To manufacture a perpendicular magnetic recording medium, a nonmagnetic substrate having a coating layer of a binder with magnetic particles dispersed therein is passed through a magnetic field in a direction substantially perpendicular thereto, and a perpendicular orientation of the magnetic particles is performed as the substrate passes through an upstream region of the magnetic field. A viscosity of the coating layer is increased in a downstream region of the magnetic field, thereby restricting further movement of the magnetic particles in the coating layer before the nonmagnetic substrate is removed from the magnetic field.
