Abstract

PURPOSE:To improve corrosion resistance and running characteristics by adsorbing metallic salt of perfluoroalkyl carboxylic acid on a thin film of a ferromagnetic material for magnetic recording. CONSTITUTION:A thin film medium for magnetic recording made of ferromagnetic metal by vacuum deposition, etc., is coated with or dipped in a solution or dispersed liquid of metallic salt such as chromium, iron, cobalt, nickel, copper, etc., of perfluoroalkyl carboxylic acid expressed by CnF2n+1COOH (where n is >=1), thus performing adsorbing reaction. As said metallic salt, trifluoroacetate nickel salt or iron salt, or pentadecafluorooctanoic acid nickel salt, iron salt, or chromium salt is usable.
