Abstract

PURPOSE: To improve resistance to wear of a magnetic layer by mixing a two- component system lubricant of α-olefin oligomer and fatty acid amide of C6W18 in the magnetic layer.
CONSTITUTION: According to the formula [R is alkyl of C2W14; (n) is an integer], α-olefin oligomer and fatty acid amide of C6W18 are mixed preferably at a weight ratio of 80:20W99:1. This two-component system lubricant dissolved in an organic solvent during or after the formation of a magnetic layer is contained in a magnetic layer preferably at a weight percent of 3W15 to magnetic powder. If 1W3 weight % of non-magnetic powder of more than 6 in Mohs' hardness is preferably used together with magnetic powder besides this lubricant, resistance to wear will improve and friction to an opposing body such as a magnetic head, etc., will also be suppressed.
