The main subjects to be solved for realizing contact recording systems are the reduction of head wear and head vibration. Although many studies have been reported about the latter, few reported on the reduction of head wear. For this purpose, we investigated pin wear on various thin-film disk surfaces. We compared roughness of disk surfaces and molecular weight (MW) of lubricants. The results showed that the pin wear became larger as the MW was smaller or roughness was large. In addition, we found the tape burnishing of disk surfaces was effective in wear reduction.
