Hertzian impact theory is used to analyze impact-induced head disk interface (HDI) contact damage. Contact parameters including penetration (media damage), contact force, contact radius, impact duration, maximum and mean contact pressure are given at different normal impact velocities and slider corner radii in the form of contour plots. The results clearly suggest that the decrease of impact velocity or the increase of corner radius could both reduce the possibility of plastic deformation due to slider (head) disk impact contact.
