A new type of flying head slider mechanisms whose air bearing surface (ABS) or disk surface has local temperature distributions such as thermal fly-height control (TFC) and heat assisted magnetic recording (HAMR) have been proposed in order to increase the recording density. Moreover, recently, He-enclosed HDDs have been researched and developed to achieve high performance, because Helium has smaller windage loss and higher heat conductivity than air. Thus, it is becoming increasingly important to analyze the flying characteristics of head sliders over a running disk using the thermo-molecular gas-film lubrication (t-MGL) equation. In this paper, we numerically calculated the static lubrication characteristics for Air/He as working fluid. We also calculated the flying characteristics for various sliders.
