Abstract

Most hard disk drives that apply the ramp load/unload technology unload the heads at the outer edge of the disk while the disk is rotating. During the unloading process, slider-disk contacts may occur by lift-off force and rebound of the slider. The main issue of this paper is to prevent the slider-disk contact by changing the state matrix. Because the state matrix is related to the suspension and slider, to change the state matrix means the structural change of the suspension and slider. We investigate influence for variation of the state matrix components and analyze the relation between the state matrix and the suspension/slider.
