Abstract
본 발명은 자기기록매체 제조방법에 관한 것으로, 카본블랙을 주성분으로 하는 백코팅도료에 α-Fe2O3를 첨가하고, 이 α-Fe2O3가 첨가된 백코팅도료를 비자성 지지체의 이면에 도포하여 백코팅층을 형성함을 특징으로 하고 있으며, 상기 α-Fe2O3는 구상으로서 입자 싸이즈는 0.2∼1.0㎛인 것을 이용하고, 상기 백코팅층은 두께 1.5∼2.5㎛로 형성한다. 이와같은 본 발명에 의하여 자기기록매체는 우수한 스티프니스(stiffness) 및 주행안정성을 가지며, 이로 인하여 전자변환성특성을 향상하는 이점이 있다.The invention of the nonmagnetic support to be carbon black to the back coat paint mainly composed of the addition of α-Fe 2 O 3, and the α-Fe 2 O 3 is a back-coating paint is added on the production method the magnetic recording medium It is characterized by coating on the back surface to form a back coating layer, wherein the α-Fe 2 O 3 is spherical, the particle size is 0.2 ~ 1.0㎛ used, the back coating layer is formed with a thickness of 1.5 ~ 2.5㎛. According to the present invention, the magnetic recording medium has excellent stiffness and running stability, thereby improving the electronic conversion characteristics.
