近年来，由于波长越来越短，数值孔径越来越大，一般光存储介质的存储容量已达到极限。因此，我们需要开发新的光存储系统。本研究提出一种多层高密度光储存媒体。该介质具有由200 nm直径的光敏颗粒组成的纳米结构。每个粒子用于数字可记录凹坑。它的光学形状信号拾取与偏振干涉非线性共焦显微镜配备了一个高数值孔径物镜。在所提出的磁盘中，时钟数据恢复不需要电子产生的参考信号。因此，在通过非周期性时钟信号的恢复中不发生抖动。
Recently, general optical-storage-media's capacity reached a limiting point due to shorter wavelengths and higher numerical apertures. Therefore, we need to develop novel optical storage system. In this research, a multi-layered high-density optical storage media has been proposed. The media has nanostructures composed of 200-nm-diameter photosensitive particles. Each particle is used for digital recordable pits. Its optical shape signal is picked up with a polarization-interferometric nonlinear confocal microscope equipped with a high numerical aperture objective. In the disk proposed, no electronically produced reference signal is necessary for clock data recovery. So, no jitter occurs in the recovery through nonperiodic clock signal.
