Abstract
PURPOSE: To suppress the exudation of a lubricant by eliminating the flutter echo of a tape in its storage or use under high-temperature and high-humidity conditions by making a magnetic layer contain liquid paraffin, specific fatty acid ester, and zinc salt of saturated fatty acid of specific C-number.
CONSTITUTION: A fatty acid ester prepared from saturated fatty acid of C-number 18 such as stearic acid-n-butyl and aliphatic alcohol of C-number 3W6, liquid paraffin, and zinc salt of saturated fatty acid of C-number 14W18 such as zinc stearate are kneaded by fixed amounts together with magnetic powder and a binder, thereby forming a magnetic layer. In another way, those are mixed with a solvent, etc., and applied or sprayed with on the previously-formed magnetic layer to form a magnetic recording medium. Consequently, a tape when used for a long time under high-temperature and high-humidity conditions has no tape flutter echo, and the exudation of a lubricant is also eliminated, so that a durable magnetic tape stable in run can be obtained.
