We investigated a design method of a flying head slider that can suppress the bouncing vibration in a near-contact regime. We numerically computed the slider dynamics of a 2-DOF slider model by using the bulk contact force, the simple adhesive force and nonlinear air-bearing stiffness. As a result, we could get the self-excited bouncing vibration whose general characteristics are very similar to the experimented results. Parametric study shows that the frictional coefficient, attractive force and contact stiffness should be decreased and front and rear air-bearing stiffness and ratio of rear to front air-bearing stiffness should be increased in order to realize a stable flying slider in a smallest possible spacing.
