Abstract
PURPOSE:To improve a traveling property, wear resistance, durability and rust preventive effect by using a mixture composed of perfluoropolyether having a carboxylic group at the terminal and specific org. amine as a lubricating agent in a back coat layer. CONSTITUTION:A thin ferromagnetic metallic film 2 is formed on a nonmagnetic base 1. A lubricating agent layer 3 consisting of the perfluoropolyether having the carboxyl group at the terminal and the org. amine expressed by R-NH2 (where R denotes a hydrocarbon group of >=3C) is deposited on the thin ferromagnetic metallic film 2. A long-period lubricating effect is thereby maintained even under various usable conditions and the magnetic recording medium which exhibits the excellent traveling property, wear resistance and durability and has the excellent rust preventive effect is obtd.
