Abstract

PURPOSE:To obtain a magnetic recording medium which has superior electromagnetic conversion characteristics, running stability and durability, by using channel black as an antistatic agent mixed into a magnetic layer. CONSTITUTION:Channel black having >=100m<2>/g gaseous nitrogen adsorption surface area and >=50cc/100g DBP oil absorption is added as an antistatic agent to magnetic paint which contains magnetic powder, a binder, a lubricant, a dispersant, a plasticizer, abrasives, etc., and the magnetic paint is applied over a base to obtain a magnetic recording medium.
