O presente artigo trata do domínio do tempo de diferenças finitas dependente da frequência ((FD)2TD) análise do método do espalhamento do feixe de luz de um modelo de disco magneto-óptico (MO) de gravação terrestre/sulco com uma camada reflexiva de Al (ALRL), a fim de melhorar a análise convencional para modelos de disco MO sob a suposição de condução reflexiva perfeita camada (PCRL). São apresentados exemplos numéricos de campos dispersos com polarização principal e cruzada e a diferença de fase entre eles. Mostramos a comparação das características de espalhamento entre ALRL e PCRL, e também examinamos a dependência da conversa cruzada do sinal de leitura devido a marcas registradas adjacentes tanto no tamanho da marca registrada quanto na profundidade das ranhuras.

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 magneto-optical (MO) disk model with an Al reflective layer (ALRL) in order to improve the conventional analysis for MO disk models under the assumption of perfectly conducting reflective layer (PCRL). Numerical examples of main- and cross-polarized scattered fields and the phase difference between them are presented. We show the comparison of the scattering characteristics between ALRL and PCRL, and also examine the dependence of the cross talk of the readout signal due to adjacent recorded marks on both the recorded mark size and the depth of grooves.
