Abstract

본 발명은 비자성지지체위에 자성입자와 접착제를 주성분으로 한 자성도료를 도포하여 자성층을 형성하고 이 자성층위에 보호층을 갖도록 하는 자기기록매체의 제조방법에 있어서, 자성도료 제조시 자성입자 교반 단계에서 비닐계 접착제와 폴리우레탄계 접착제를 연속적으로 투입 교반 후 분산공정을 실시함을 특징으로 하는 자기기록매체의 제조방법을 제공하는 것으로, 본 발명에 의하면 도료 제조 소요시간이 단축되어 생산성이 매우 향상될 뿐만 아니라, 도료특성과 전자특성 등 제특성 또한 우수해지는 잇점을 지닌다.The present invention is a method of manufacturing a magnetic recording medium in which a magnetic layer comprising magnetic particles and an adhesive as a main component is applied onto a nonmagnetic support to form a magnetic layer, and having a protective layer on the magnetic layer. The present invention provides a method for manufacturing a magnetic recording medium, characterized in that a dispersion process is performed after stirring and continuously adding a vinyl adhesive and a polyurethane adhesive, and according to the present invention, the time required for manufacturing a paint is shortened, thereby greatly improving productivity. In addition, it also has the advantage that various properties such as paint characteristics and electronic characteristics are also excellent.
