We analyzed the optimum structure of recording media for a reflection confocal readout system of three-dimensional optical memory. In this analysis, we discuss the overlapping regions of the coherent transfer function of the reflection confocal readout system and the spatial frequency distribution of recorded bits. The intensity of the readout signal is proportional to the multiplication of the three-dimensional distribution of the coherent transfer function of the reflection confocal system and the spatial frequency distribution of recorded bits. We optimized film thickness to increase the signal from recorded bits. It was found that the readout signal increased twentyfold by optimization of film thickness. In addition, we optimized the relative refractive index of recording media by light propagation analysis of multilayered media. In the case of optimal film thickness, the ratio of refractive indices between recording layers and transparent layers should be 1.01 for obtaining maximum reflection.
