As the contact slider system has a high area density, this system will be used in future high performance drives. So the dynamic characteristic research for this system is an important issue. The contact slider system is modeled as 2-DOF mathematical model. When slider contacts on disk surface, simulation is performed with contact governing equation. The formula for contact is derived by numerically Green's function of a semi-infinite elastic body over the contact surface. Otherwise, when the slider flies over disk surface, the analysis is carried out with flying governing equation. Disk surface is composed by the practical disk amplitude with SPM (scanning probe microscopy). Through this model, the flying stability of contact slider are investigated for various parameters.
