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.

摘要： A magnetic recording medium is disclosed comprising a substrate coated with a mixture which consists essentially of (1) hexagonal plate-like shaped, ferrite magnetic powder particles having an average particle diameter of 0.2 .mu.m or less and (2) a binder resin having an active hydrogen equivalent of 2000 or more. This magnetic recording medium displays no flocculation of the hexagonal system ferrite magnetic powder, and has excellent dispersion properties and perpendicular orientation ability. Further, smoothness on the coating film is good, and S/N properties are noticeably improved.
