Abstract

본 발명은 자기기록매체의 제조방법에 관한 것으로서, 자성체, 결합제, 연마제 및 용제를 포함하는 자성도료를 비자성 지지체 기재의 상부에 도포, 건조시켜 자성층을 형성하여 되는 자기기록매체의 제조방법에 있어서, 상기 연마제를 미리 자성층 제조시에 사용되는 것과 동일한 결합제에 분산시켜 도료화하여 사용하는 것을 특징으로 하는 자기기록매체의 제조방법에 의하여 제조된 자기기록매체는 자기특성, 표면평활성, 내구성 등의 제반특성이 향상된 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a magnetic recording medium, wherein a magnetic layer comprising a magnetic material, a binder, an abrasive, and a solvent is applied to an upper portion of a nonmagnetic support substrate and dried to form a magnetic layer. The magnetic recording medium manufactured by the method of manufacturing a magnetic recording medium, wherein the abrasive is dispersed in a same binder used in the preparation of the magnetic layer in advance and used as a coating material, has various characteristics such as magnetic properties, surface smoothness and durability. The property is improved.
