Abstract

본 발명은 자기기록매체의 제조방법에 관한 것으로서, 자성체, 수지 용제 및 연마제를 포함하는 자성도료를 비자성 지지체 기재의 상부에 도포, 건조시켜 자성층을 형성하여 되는 자기기록매체의 제조방법에 있어서, 상기 연마제가 평균 입경 0.19㎛의 알루미나와, 혼합 총량 100 중량부에 대하여 10 내지 50중량부의 평균 입경 0.25㎛의 알루미나를 혼합하여 되는 기기록매체의 제조방법이 개시된다. 얻어지는 자기기록매체는 자기 특성, 주행성, 내구성 등이 향상된 것이다.The present invention relates to a method of manufacturing a magnetic recording medium, wherein a magnetic coating comprising a magnetic material, a resin solvent, and an abrasive is applied and dried on an upper portion of a nonmagnetic support substrate to form a magnetic layer. Disclosed is a method for producing an instrument recording medium in which the abrasive is mixed with alumina having an average particle diameter of 0.19 µm and alumina having an average particle diameter of 0.25 µm by 10 to 50 parts by weight based on 100 parts by weight of the total amount. The resulting magnetic recording medium has improved magnetic properties, runability, durability, and the like.
