Development of a Numerical Simulation System to Evaluate Flying Characteristics of Head Sliders for Magnetic Disk Storage

In the present research, we developed an interactive numerical simulation system for evaluation of static and dynamic characteristics of a flying head slider under nano-meter spacing conditions. This system enables rapid and efficient calculation while changing parameters that affect the numerical solution of the fundamental equations. The system also supports several types of sliders and patterned disk surfaces as well. Furthermore, the upstream finite difference method is applied to the Couette flow term instead of the conventional central finite difference method, and the convergence of the pressure solution is found to be much improved.
