Slider flying height has been reduced to less than 2 nm to increase the recording density of hard disk drives (HDDs). However, it is demanded that the flying height should be reduced more. On the other hand, the helium-filled HDD was proposed to resolve the positioning error and reduce the electricity consumption. In the helium-filled HDD, the wear properties of slider surface covered with diamond like carbon(DLC) may be different from the wear properties in air, because it has no oxygen. In this paper, we investigate wear properties of sliders as a function of relative amount of gases (water, Vertrel-XF, and ethanol) in atmospheric air and nitrogen.
