Abstract
PURPOSE: To suppress the exudation of a lubricant by eliminating the flutter echo of a tape in its storage and use under high-temperature and high-humidity conditions, by making a magnetic layer contain liquid paraffin, specific fatty acid and zinc salt of saturated fatty acid of specific C number.
CONSTITUTION: A fatty acid of C-number 14W18 such as a myristic acid and liquid paraffin are mixed together at a ratio of 8:2W2:8 before zinc salt of saturated fatty acid of C-number 14W18 such as zinc stearate or the like of equivalent weight approximately 1/3 to 1 as much as the total weight of the both is added, and they are kneaded together with magnetic powder and a binder to form 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 ehco, and the exudation of a lubricant is also eliminated, so that a durable magnetic tape stable in run can be obtained.
