  Abstract

Unlike storage systems that store information on a volume, holographic data storage has high data processing speed, large capacity, and high data transfer rates because it stores data on a page-by-page basis in the volume of the media. However, because several images are stored in the same hologram space, inter-page interference occurs, and because data is processed in units of two-dimensional pages, two-dimensional inter-symbol interference also occurs. If the ratio of ON pixels per page is around 25%, the storage capacity of a holographic data storage system can be increased by 15%. In this paper, we propose modulation codes with a same code rate of 2/3 to increase the number of pages in a volume by lowering the ratio of ON pixels recorded on a page to increase the storage capacity of the holographic data storage system.
