Abstract

This paper suggests a mode of the heat transfer between hybrid recording medium and the sliding air film. According to the differential theory and the symmetrical theory, the energy of the laser heating can be removed in subsection; the laser power from waveguide in track can be looked as the power in a moment. So we can get the simulation results of the average temperature of the medium. Since hybrid recording head gap is less than 20nm, the temperature gradient field of air film can be simulated by boundary layers theory. This paper simulated air film temperature heated by the near field optical in hybrid recording. The results show that air film heating-up has influence on the slider bearing system, such as fly height and pose. The simulation of the slider fly height and pose illuminate that in the extreme the effect of heating-up of the air film on fly height and pose must be emphasized enough.
