An indirect assessing method of wear progress on a magnetic disk surface was developed. The applicable amount of worn volume is limited to the order of roughness amplitude in 2-dimensions which can be measured by a stylus instrument with light load. Having established the physical measuring conditions and statistical sampling ones, several kinds of topographic parameters based mainly on asperity tip geomrtry were proposed such as radius of asperity tip, slope of the peak. tip segment area and mean gap between two adjoining peaks. Furthermore, a distinctive method for selecting higher peaks which are related to the contact with a head was developed. The values of these parameters were obtained on the Contact Start/Stop experiments and they were Verified to be effectual to distinguish the surface textures and assess the wear progress in a more quantitative way.
