Much attention has been focused on the effects of the disk substrate in optical data storage. In particular, substrate birefringence has been studied extensively because it causes significant problems in magneto-optic systems. We investigate certain subtle effects of the substrate, such as feedback into the laser diode, in compact disk and phase-change systems. Our analysis of the compact disk system led us to discover a new technique for the rapid measurement of the substrate birefringence. We also address the question of how focusing the laser beam through the substrate will affect the depth of focus.
在光学数据存储中，磁盘基板的影响已备受关注。特别是，基板双折射已得到广泛研究，因为它在磁光系统中会引发重大问题。我们研究了基板的某些微妙影响，例如在光盘和相变系统中反馈到激光二极管的情况。我们对光盘系统的分析使我们发现了一种快速测量基板双折射的新技术。我们还探讨了激光束透过基板聚焦如何影响焦深的问题。
