Abstract
This paper describes the dynamics of contact sliders with nano textures fabricated by femto second laser processing. First of all, the femto second laser processing method was developed in order to fabricate the texture on the DLC thin film pad. The contact slider experiments were carried out by using the slider with nano-textures, and the influences of nano-textures on the friction and slider dynamic characteristics were investigated in DTK disk as well as in Flat disk. As a result, the friction and vibration characteristics have been remarkably improved by the texture in both disks. And it was suggested that the optimum values of the height and area ratio of the texture were existed.
