Abstract
PURPOSE: To prepare a magnetic recording medium which is satisfactory in its running quality and has little output fluctuation, by treating the magnetic metal film vapor-deposited on the substrate surface by use of a treatment solution which has been prepared by adding higher fatty acid and one kind or more of its metallic salt to a nonpolar organic solvent, and subsequently washing it.
CONSTITUTION: For instance, a regular film magnetic tape is prepared by forming a metallic film on the substrate surface such as a polyester film as a type by vapor- depositing a magnetic metal through the oblique vapor deposition method or the oblique incident ion plating method. This tape is treated by a treatment solution which is made by adding higher fatty acid and one kind or more selected from its metallic salt to a nonpolar organic solvent, and the monomolecular layer of higher fatty acid or its metallic salt is chemically adsorbed onto the metallic film surface with its long chain outside. And excess higher fatty acid or its metallic salt which is not adsorbed is removed by washing it with a detergent.
