Abstract

A magnetic recording material having excellent magnetic properties and excellent abrasion resistance is proposed. The material consists of a non-magnetic medium having a thin ferromagnetic metal film formed thereon as a magnetic recording layer by means of a vacuum deposition or ion plating process. The thin ferromagnetic metal film contains Co as the main component and 0.1 to 5.0 atom % of at least one of the elements Mo, Ta and/or W.
