| Abstract: | An integrated numerical scheme was proposed for the simulation of optical flying head (OFH) dynamics in near-field optical recording (NFOR) system. The control volume method was employed to obtain the pressure distribution of the air bearing slider (ABS) with complicated surface and the Quasi-Newton iteration method was utilized to search the stable flying attitude of optical flying head. Furthermore, the effects of the main parameters of ABS on the stable flying attitude were investigated by the numerical scheme and the optimization of slider surface profile is implemented. The results demonstrate that the OFH can achieve stable flying height (73.87nm) and flying attitude, which meets the requirement of NFOR system. |
