Abstract

본 발명은 자기기록 매체의 제조 방법에 관한 것이다. 메틸에틸케톤, 톨루엔 및 사이클로헥사논을 포함하는 유기용제, 자성체, 카본블랙, 연마제, 결합제, 윤활제 및 경화제를 함유하는 자성도료를 비자성 지지체 위에 도포, 건조, 캘린더링, 슬리팅하는 것을 포함하는 자기기록 매체의 제조 방법에 있어서, 상기 자성도료가, 상기 톨루엔에 대한 상기 메틸에틸케톤의 비율이 1 이하인 자성체 분산용 유기용제를 제조하는 단계, 상기 단계에서 제조된 상기 유기용제를 상기 자성체 고형분에 투입, 분산시켜 자성체 분산액을 제조하는 단계 및 상기 분산액, 상기 연마제, 상기 결합제, 상기 경화제, 상기 윤활제 및 상기 유기용제를 혼합, 분산하는 단계를 통하여 얻어지는 것을 특징으로 하는 자기기록 매체는 전자특성이 뛰어나다.The present invention relates to a method of manufacturing a magnetic recording medium. Applying, drying, calendering, and slitting a magnetic paint containing an organic solvent, a magnetic substance, carbon black, an abrasive, a binder, a lubricant, and a curing agent, including methyl ethyl ketone, toluene, and cyclohexanone, onto a nonmagnetic support. A method of manufacturing a magnetic recording medium, wherein the magnetic paint prepares an organic solvent for magnetic body dispersion in which the ratio of methyl ethyl ketone to toluene is 1 or less, wherein the organic solvent prepared in the step is added to the magnetic solid content. A magnetic recording medium obtained by adding and dispersing to prepare a magnetic dispersion and mixing and dispersing the dispersion, the abrasive, the binder, the curing agent, the lubricant and the organic solvent has excellent electronic characteristics. .
