Abstract
본 발명은 자기기록매체의 제조방법 및 자기기록매체에 관한 것으로, 제조방법은 지지체 상에 접착력을 증가를 위한 접착재료에 카본블랙을 함유시킨 언더코팅재로 언더코팅층을 형성하고, 카본블랙을 제외시킨 자성도료를 코팅하여 자성층을 형성함을 특징으로 하고 있으며, 상기 언더코팅재는 접착재료에 대하여 카본블랙을 30중량%에서 300중량%로 첨가하고 상기 언더코팅층을 두께 0. l㎛-2.5㎛로 형성하는 것을 특징하고 있다. 이러한 본 발명은 비디오테이프 자성층 중에 카본블랙을 제거하여 전자변환특성을 향상시키고 이에따라 발생되는 접착력, 광투과 및 표면전기저항 문제는 카본블랙을 중성분으로 하는 언더코팅을 실시함에 의해 해결함으로써 선명한 화질과 기능상에 하자가 없는 양호한 자기기록매체를 제공할 수 이는 이점이 있다.The present invention relates to a method for manufacturing a magnetic recording medium and a magnetic recording medium, wherein the manufacturing method includes forming an undercoat layer with an undercoating material containing carbon black in an adhesive material for increasing adhesion on a support and excluding carbon black. The magnetic coating is coated to form a magnetic layer. The undercoating material is added with carbon black from 30% by weight to 300% by weight with respect to the adhesive material, and the undercoat is formed with a thickness of 0.1 μm-2.5 μm. It is characterized by. The present invention improves the electron conversion characteristics by removing the carbon black in the video tape magnetic layer and solves the problems of adhesion, light transmission, and surface electrical resistance caused by undercoating with carbon black as a heavy component. This has the advantage that it is possible to provide a good magnetic recording medium with no defects in function.
