Abstract

본 발명은 자기기록매체의 제조방법에 관한 것으로 더욱 상세히 설명하면 강자성 분말, 대전 방지제 및 연마제 등의 입자를 고분자 용액에 분사시킴에 있어서 분산성이 우수하고, 이로 인하여 제조된 테이프의 전자변환 특성, 내구성이 우수하고, 특히 드롭아웃트의 결점을 최소화 또는 없게 하는 자기기록매체의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a magnetic recording medium, which will be described in more detail. Injecting particles such as ferromagnetic powder, an antistatic agent, and an abrasive into a polymer solution has excellent dispersibility, and thus the electron conversion characteristics of the manufactured tape, The present invention relates to a method of manufacturing a magnetic recording medium which is excellent in durability and particularly minimizes or eliminates defects of dropouts.

본 발명은 비자성 지지체 표면에 강자성 분말, 연마제, 대전 방지제, 윤활제 및 기타 첨가제를 결합제 수지에 고분산시켜 제조한 자성 도료를 도포하여서 자기기록 매체를 제공한다.The present invention provides a magnetic recording medium by applying a magnetic paint prepared by highly dispersing ferromagnetic powder, an abrasive, an antistatic agent, a lubricant, and other additives to a binder resin on a nonmagnetic support surface.
