Abstract

PURPOSE: To increase the lubricity of tape at high moisture and durability of still reproduction and to prevent the sealing dirt of magnetic tape, by including specific fatty acid, fatty acid ester and unsaturated fatty acid amide to the magnetic substance layer.
CONSTITUTION: To the magnetic coating liquid essentially composed of ferromagnetic fine powder and coupling agent, one or more compounds consisting of saturated and unsaturated acid of C-number 12W22 (e.g. oleic acid), one or more compounds consisting of saturated and unsaturated fatty acid ester of C-number 14W22 for fatty acid residue (e.g. n-butylstearate) and one or more of unsaturated fatty acid amides of C-number 18W26 (e.g., trichoseneamide) are added and dispersed by mixing. This magnetic coating liquid is coated on the support and dried to provide the magnetic substance layer. Since this magnetic recording medium has low friction condition at each condition, the running tension at high moisture can be reduced.
