摘要：
The dependence of readout signal from embossed grooves on edge decline is studied by a simulation method. The disk is modeled as one-dimensional grating that consists of grooves with declining wall. The formula of readout signal is derived based on vector diffraction theory, then the effect of the wall decline is investigated. The simulation shows that the effect of wall decline depends on the polarization of incident light. When the electric vector of the incident light is perpendicular to the groove wall, the decline mainly influences the peak-valley value and the increasing rate of the readout signal. When the electric vector is parallel with the groove wall, the decline mainly influences the amplitude of readout signal.
