| Abstract(in English) | Recently, a short wavelength laser and a narrow track pitch are used to realize a higher density version of optical disk. However, using narrow track pitch can cause the increase of the crosstalk from the adjacent tracks. Moreover, the use of narrow pitch and short wavelength can also give rise to the increase of deterioration of the detected signal characteristics due to the microscopic roughness of disk surface. In this paper, in order to estimate the effect of surface roughness, we deal with the Finite Difference Time Domain (FDTD) method analysis of light beam scattering and detected signal characteristics of phase-change optical disk models with random rough surfaces. |
