全息数据存储是一种很有前途的技术，可以提供非常大的数据存储容量，而复用方法在增加这种容量方面发挥着重要作用。先前已经研究了各种复用方法。在本研究中，我们提出了一种使用球形参考波的平移周转复用技术，并通过实验验证了该方法有效地增加了数据容量。在所提出的方法中，通过移位复用记录一系列全息图，其中记录材料以其轴垂直于材料表面的方式旋转。通过迭代此过程，多样性得到改善。该方法实现了超过1 Tbits/inch2的数据密度记录。此外，通过最大限度地提高记录介质的性能，预计每个磁盘的容量将增加数TB。
Holographic data storage is a promising technology that provides very large data storage capacity, and the multiplexing method plays a significant role in increasing this capacity. Various multiplexing methods have been previously researched. In the present study, we propose a shift-peristrophic multiplexing technique that uses spherical reference waves, and experimentally verify that this method efficiently increases the data capacity. In the proposed method, a series of holograms is recorded with shift multiplexing, in which the recording material is rotated with its axis perpendicular to the material’s surface. By iterating this procedure, multiplicity is shown to improve. This method achieves more than 1 Tbits/inch2 data density recording. Furthermore, a capacity increase of several TB per disk is expected by maximizing the recording medium performance.
