Abstract
PURPOSE: To improve resistance to wear of a magnetic layer by mixing a two- component system lubricant made of α-olefin oligomer and higher fatty acid in a solid state under an oridinary temperature into the magnetic layer.
CONSTITUTION: In accordance with the formula (R is alkyl of C2W14; n is an integer), α-olefin oligomer and fatty acid in a solid state under an ordinary temperature are mixed, preferably, at a weight ratio of 80:20W99:1. In or after the formation of the magnetic layer, this lubricant is contained in the magnetic layer to 3W 15wt% to magnetic powder being dissolved in an organic solvent. Further, adding non-magnetic powder of more than six in Mohs' hardness to the magnetic powder of more than six in Mohs' hardness to the magnetic powder, preferably, to 1W 3wt% improves resistance to wear and also suppresses abrasion of a contact object such as a magnetic head.
