Change in Surface Tension and Pin Wear Characteristics of Thin-Film Disks by Heat Treatment and UV Irradiation

The lubricant on thin-film disks is a key material for disk durability. Bonded lubricant layer remains on disk surfaces after solvent rinsing which removes mobile lubricant. To improve disk durability, lubricant treatments comprising heat treatment and UV irradiation, have been studied. Both of them...
