Abstract
PURPOSE: To enhance both the half-life and orientation properties as well as to increase the film intensity by using the magnetic powder the surface of which is coated with the mixture of the quaternary ammonium chloride and phosphate of the alcohol.
CONSTITUTION: The magnetic recording medium is made by coating the magnetic coating material formed in the following method onto the substrate of polyester or the like. The mixture of the quaternary ammonium chloride as shown by Eq.I plus the phosphate of the alcohol of under 50wt% to the full active agent quantity is coated over the surface of the magnetic power as the antistatic agent. Then the magnetic coating material is obtained by mixing the magnetic powder composed as described above and the binder containing the vinyl chloride-vinyl acetate polymer which is plasticized by the nitrile butadiene rubber. As a result, a magnetic recording medium can be obtained, featuring the sufficiently short half-life, an extremely high orientation property and a high head adhesive force.
