Abstract

PURPOSE: To obtain a magnetic coating of specific thickness or less by using a coating material of specific solid-part concentration using a low-boiling-point solvent including a high-boiling-point solvent in a means of manufacturing a magnetic recording medium that applies the magnetic with magnetic fields parallel and perpendicular to the surface of the base.
CONSTITUTION: A magnetic coating material that includes 10W25wt% solid matter, consisting of magnetic particles and resin, in a low-boiling-point solvent of 160°C or less in boiling point which includes a 15W30wt% high-boiling-point solvent of 160W230°C in boiling point, such as alcohol, ketone and polyhydric alcohol is applied onto substrate 4 by coating device 6 and then the base is passed through vertical magnetic-field magnet 11 and oriented magnetic-field magnet 7 and dried by drier 8 to obtain a magnetic coating of 1μm or less in thickness.
