Filed: 1980-04-03
Abstract: PURPOSE:To reduce the sticking of magnetic powder onto a magnetic head while eliminating the tape squeal of a magnetic recording medium by applying magnetic coating, obtained by kneading magnetic powder coated with glyceride together with a bonding agent, onto a base. CONSTITUTION:Glyceride as a surface active agent, magnetic powder and a solvent or water are mixed sufficiently with stirring in a mixer or kneader to adsorb the surface active agent to the surface of the magnetic powder. Next, the mixture is dried with heating to coat the surface of the magnetic powder with the surface active agent. This coat-treated magnetic powder is dispersed and mixed in a dispersing machine together with a bonding agent, such as a prepolymer and synthetic resin, and a solvent. The magnetic coating obtained is applied onto the surface of a polyester base film and then dried to manufacture a magnetic tape. This tape has low kinetic friction resistance, a small secular increase and no tape squeal, and the sticking of the magnetic powder onto a magnetic head is reduced.
