Abstract

The holographic data storage system stores multiple data pages by multiplexing. But the inter-page interference(IPI) caused by multiplexing reduces the intensity of the hologram. The simulation of the holographic storage systems has to consider the IPI. Therefore, we introduce a channel modeling that takes care of inter-page interference in the holographic data storage system. We simulate the performance of PRML detection on the hologrpahic data storage system with IPI modeling.

홀로그래픽 저장장치는 여러 장의 데이터 페이지가 멀티플랙싱 기법에 의하여 같은 공간에 저장된다. 그러나 이러한 데이터 저장 밀도의 증가에 따라 페이지 데이터들이 서로에게 간섭이 된다. 같은 공간에 저장되는 모든 페이지들이 서로 간섭을 주게 되며, 그에 대한 영향력을 실험 과정에서 고려해야 한다. 따라서 본 논문에서는 이러한 페이지 간의 간섭에 대한 모델링을 하며, 그에 대한 성능을 분석한다.
