详细介绍了一种用于光盘存储系统精确分析的三维光电磁时域有限差分（FDTD）模型。该模型不仅考虑了磁光盘和相变光盘等典型光存储系统的复杂材料特性，而且考虑了复杂的非周期性光盘结构。此外，该模型使我们能够考虑高数值孔径的光存储系统，这是一个必要的考虑近场光记录。以光学ROM、相变光盘和MO盘为例，说明了该模型的实用性。
A rigorous three-dimensional optical electromagnetic finite-difference time-domain (FDTD) modeling for the accurate analysis of an optical disk storage system is detailed. In this model, not only the complex material properties of typical optical storage systems, such as the magneto-optical (MO) disk and the phase-change optical disk, but also the complex aperiodic disk structure is considered. Moreover, the model enables us to consider the high-numerical-aperture optical storage system, which is a necessity in the consideration of the near-field optical recording. Numerical investigations of the optical ROM, the phase-change optical disk and the MO disk are presented as examples to demonstrate the utility of the model.
