The optical disc and its readout system are analyzed. Rigorous mode method is used to set up a mathematical model of the optical disc diffraction process. The proposed Portran-77 computing programs using the appropriate numerical techniques can provide rapid, detailed and numerical solutions. The computing results are in good agreement with those of experiments.
