| Research Abstract |
For the development of next generation optical disk memory, we succeeded to achieve storage capacity of 4.35TB by using a confocal scheme that is 3.36 times larger than that without the confocal scheme in a reflection-type holographic memory with three-dimensional speckle shift multiplexing. In page data coding, we increased the amount of data in one page by 1.5 times larger by proposing multi-resolution data coding. These results indicated that it is possible to achieve storage capacity of 1TB by combining these methods.
