MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To improve corrosion resistance by contg. a volatile corrosion preventive material in a back coating layer. CONSTITUTION:A thin magnetic film obtd. by vacuum deposition or the like or a magnetic layer obtd. by dispersing magnetic metals or alloys in a binder is formed on a non-magnetic substrate of polyethylene terephthalate or the like and a back coating layer using a resin binder or the like contg. dicyclohexyl ammonium nitride or other volatile corrosion preventive materials is formed on the rear surface of the substrate.
