摘要

Owing to the drastic advances in information technology, the development of fast, high-density 3D optical data storage is a key issue. Consequently, much attention has been paid to multilayered recording to realize 3D data storage. Meanwhile, holographic recording, by which information is stored as an optical interference pattern produced by two intersecting coherent object and reference beams, serves as a valuable method for optical data storage. Therefore, holographic recording into a multilayered medium constitutes a highly promising approach for the realization of 3D optical memory with excellent performance. However, conventional holographic recording systems cannot be applied to this approach because the information recorded into a layer is erased when a read/write process is effected on other layers.
