• 論文の詳細を見る

• In recent years, the scattering of an optical beam from pit and emboss marks of optical disk models has attracted much attention for achieving higher-density version of conventional CD-ROM type of optical disks. The present paper treats two different shapes of pit and emboss as the marks of recorded signal, i.e., cylinder type and conical trapezoid type. The readout characteristics of sum and differential signals are calculated by solving the three-dimensional integral equation.
