Abstract
본 발명은 자기기록매체에 관한 것이다. 일반적인 자기기록매체의 제조 기술은, 자성 분말의 흡착량이 많아지게 되면, 자성 도막의 내구성은 향상되나, 자성 분말의 분산이 어려워지며, 반면에 자성 분말의 흡착량이 적어지게 되면, 분산성은 향상되지만 도막의 내구성이 저하되는 문제점이 있었다. 본 발명은 자성 분말 비표면적(BET)이 45㎡/g이고, 항자력(Hc)이 900 Oe이상인 강자성 분말에 Si 함량을 1∼3%의 범위에서 표면 처리함으로써 자성분말의 분산성과, 도막 제조 후, 내구성을 향상시킴은 물론, 전자 변환 특성을 동시에 만족시키도록 한 것이다.The present invention relates to a magnetic recording medium. In general, the magnetic recording medium manufacturing technique increases the adsorption amount of the magnetic powder, which improves the durability of the magnetic coating film, but makes it difficult to disperse the magnetic powder. There was a problem that the durability of the. In the present invention, the magnetic powder has a specific surface area (BET) of 45 m 2 / g and a ferromagnetic powder having an anti-magnetic force (Hc) of 900 Oe or more, and surface treatment of Si content in the range of 1 to 3%, dispersibility of the magnetic powder, and after the coating film production In addition to improving the durability, it is to satisfy the electron conversion characteristics at the same time.
