Paper Abstract

We describe a FMM (Fourier Modal Method) based rigorous vector diffraction method that can be applied to trapezoidal groove structures. Applying this method to the calculation of the electric field on the surface of the recording layer for DVR groove-only recording media, we found a significant difference of the electric field distributions between two recording schemes, one when the light spot is focused on-groove, the other when it is focused in-groove. These calculation results clearly explained the measured differences of the recording power sensitivities and the cross-writing characteristics between the two schemes.
