Abstract

In the optical drive system, adopting the optical-flying-type head (OFH) flying on a removable plastic disk, the flying stability of the small OFH should be carefully considered to ensure the reliability for the first surface recording. This study gives two simulation results on the flying stability of the OFH: one is the dependence of the flying height and pitch angle variations on the wavelength and amplitude of disk waviness, and the other is the flying stability of the slider and suspension system during the dynamic load/unload process.
