Abstract

비자성 지지체 상에 강자성체 분말, 연마제, 분산제, 대전방지제 및 유기용매 등으로 구성된 자성도료를 도포하여서 얻어진 자기 기록 매체의 제조방법에 있어서, 상기한 자성도료의 분산공정 이전에 자성도료 혼합물을 60도 표면 광택도가 30% 이상이 되도록 습윤시키는 것을 특징으로 하는 자기 기록 매체의 제조방법으로서, 본 발명에 의해 제조되는 자기 기록 매체는 분산공정에서 분산성이 크게 향상됨으로 인하여 내구성, 주행성, 내마모성 및 전자변환특성이 우수하다.In the method of manufacturing a magnetic recording medium obtained by applying a magnetic coating composed of a ferromagnetic powder, an abrasive, a dispersant, an antistatic agent, an organic solvent, and the like on a nonmagnetic support, the magnetic coating mixture is subjected to 60 degrees before the magnetic coating dispersion step. A method of manufacturing a magnetic recording medium characterized by moistening the surface glossiness to be 30% or more, wherein the magnetic recording medium produced according to the present invention has excellent durability, running resistance, wear resistance, and electronic properties due to the greatly improved dispersibility in a dispersion process. Excellent conversion characteristics.
