The cross-couplings between focus and radial tracking servos in compact disc players are important, but the optical cross couplings are not well described in the literature. In this paper an optical model of a compact disc player based on the three beam single foucault detector principle is found. The general principle of the three beam focus and radial detector system is first described, followed by a non-linear static model of the relationship between the detector signals as outputs and focus… CONTINUE READING
