Abstract

본 발명은 자기기록매체에 관한 것으로, 비자성 지지체상에 제1자성층 및 제2자성층이 도포된 자기기록매체에 있어서 제1자성층 및 제2자성층의 열무게 감량(TGA)치를 특정하여 제1자성층은 경화반응이 완전히 일어나 내구성이 우수하게 하고 제2자성층은 점착이 없고 주행성이 우수하게 하므로써 전자변환특성, 주행성 및 주행 내구성이 향상된 자기기록매체에 관한 것이다.The present invention relates to a magnetic recording medium, wherein a magnetic weight loss (TGA) value of a first magnetic layer and a second magnetic layer in a magnetic recording medium coated with a first magnetic layer and a second magnetic layer on a nonmagnetic support is used to determine a first magnetic layer. The present invention relates to a magnetic recording medium having improved electron conversion characteristics, running properties and running durability by making the curing harden completely and making the durability excellent and the second magnetic layer having no adhesion and excellent running performance.
