- 論文の詳細を見る
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.
