Abstract

본 발명은 주행성 및 내마모성이 향상된 자기기록 매체를 제공하는 것으로 비자성 지지체상에 자성층을 갖는 자기기록 매체에 있어서, 자기기록 매체가 그 백코팅층에서 카본블랙 100중량부에 대하여 평균입자경이 0.1~0.3㎛인 탄산칼슘과 알루미나 혼합물을 1~5중량부 함유시키는 것이며 동마찰계수, 스틸특성 및 가이드핀스크래치가 우수하다.The present invention provides a magnetic recording medium having improved running and abrasion resistance. In the magnetic recording medium having a magnetic layer on a nonmagnetic support, the magnetic recording medium has an average particle diameter of 0.1 to 0.3 with respect to 100 parts by weight of carbon black in the back coating layer. It contains 1 to 5 parts by weight of a mixture of calcium carbonate and alumina, which are µm, and has excellent dynamic friction coefficient, steel characteristics and guide pin scratch.
