Abstract

PURPOSE:To obtain sufficient wear resistance and corrosion resistance and to uniformly form a lubricating layer so that long-term use is enabled by providing a sialon layer on the magnetic layer on a substrate. CONSTITUTION:The sialon layer 3 is formed as a protective film by a sputtering method to a 10-50nm range on the magnetic layer 2 formed on the substrate 1 consisting of an aluminum sheet, etc., and the lubricating layer 4 consisting of fluorocarbon, etc., is provided thereon. This sialon layer 3 is a sintered body layer consisting of 4 elements; silicon, aluminum, oxygen and nitrogen and has the excellent mechanical strength as the protective film as well as the good characteristics in the corrosion resistance and wear resistance and, therefore, the CSS characteristic is improved. Since the sialon layer 3 absorbs well the lubricant, the uniform lubricating film is formed and the long-term use is enabled.
