Magnetic recording medium

摘要

A magnetic recording medium is described, comprising a nonmagnetic support having thereon a first magnetic layer and having on the first magnetic layer a second magnetic layer, in that order, said second magnetic layer comprising a magnetic particle, a binder, abrasive particles and carbon black having an average primary particle diameter of 80 m mu or more, said first magnetic layer comprising a magnetic particle, a binder and carbon black having an average primary particle diameter of 40 m mu or less without substantially containing abrasive particles in the first magnetic layer, and the thickness ratio of the first layer to the second layer, first layer thickness/second layer thickness is 1.8 or more.
