Abstract: PROBLEM TO BE SOLVED: To manufacture an optical information recording medium having a recording layer whereupon information of a large quantity can be recorded by a simple system. SOLUTION: Two light transmitting substrates whereupon a first photosensitive polymer and a second photosensitive polymer are developed, respectively, are bonded to each other on the photosensitive polymer layers to form one recording layer. Since the recording layer has a larger optical absorptance as the optical focal point for information recording moves deeper in the depth direction, information can be recorded without reducing information record transfer rate.

Abstract translation: 要解决的问题：制造具有记录层的光学信息记录介质，因此可以通过简单的系统记录大量的信息。 解决方案：分别在感光性聚合物层上彼此结合两个透光性基板，第一感光性聚合物和第二感光性高分子彼此结合，形成一个记录层。 由于当信息记录用光焦点在深度方向上移动得更深时，由于记录层具有较大的光吸收率，所以可以在不降低信息记录传送速率的情况下记录信息。 版权所有（C）2009，JPO＆INPIT
