Abstract

The results of computer simulations pertaining to the offset of the point of peak irradiance from track center and the accompanying change of the tracking error signal (TES) amplitude was reported. In an optical disk drive, both disk tilt and objective lens tilt induce tracking difficulties. The effects of disk tilt on tracking servo are more severe than those of the objective lens tilt because the displacement of the focused spot caused by disk tilt is over twice that caused by lens tilt and because the focused spot is more asymmetric in the presence of disk tilt compared to the case of lens tilt.
