MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To obtain a magnetic recording medium having the excellent durability of slipperiness by forming a fluoride glass layer on a thin ferromagnetic metallic film provided on a nonmagnetic substrate. CONSTITUTION:This magnetic recording medium is formed with the fluoride glass layer 3 on the thin ferromagnetic metallic film 2 provided on the nonmagnetic substrate 1. The fluoride glass is the glass consisting of a fluoride which is excellent as a solid lubricating agent or the glass dispersed with the fluoride in other glass. The loss of the fluoride which is the lubricating agent from the glass surface is, therefore, obviated even if the magnetic recording layer formed with the fluoride glass layer is worn by a magnetic head, etc. The magnetic recording medium having the excellent durability of slipperiness is thus obtd.
