Abstract
The present paper deals with the frequency-dependent finite difference time domain ((FD)2TD) method analysis of the light-beam scattering from a land/groove recording phase-change (PC) optical disk model with a metal (Al or Au) reflective layer in order to improve the conventional analysis for PC optical disk models with a perfectly conducting reflective layer (PCRL). The scattered fields are numerically calculated for both recorded and non-recorded states of the recording layer, and the comparison of the scattering characteristics between two states is discussed. The crosstalk between the recording marks on lands and grooves are evaluated and the optimum groove depth is examined
