Abstract
PURPOSE:To obtain a magnetic recording medium which has superior running characteristics and curling characteristics, by adding quaternary ammonium salt, which has >=1 phenyl group at a cationic part, to a magnetic layer as an antistatic agnet. CONSTITUTION:About <=5wt% quaternary ammonium salt to magnetic powder, expressed by right general formula [I] is added to a magnetic layer.
