Abstract (in Japanese) (See Japanese page) 
(in English) Holographic memory is a promising technology as the next-generation optical data storage because of its advantages including large capacity, high data-transfer rate, and long archival life of recording media. We have been studying on the holographic memory for video archiving use, and demonstrated recording / reproducing data pages using a data page format with binary symbol. For further increase of capacity and data-transfer rate, recording and reproduction using a data page format with multi-level symbol is essential. Because the multi-level symbol detection is more severe than binary symbol’s case, noise reduction methods for multi-level detection are required for maintaining low bit-error rate enough for capability of error correction code. In this report, we investigate the fixed pattern noise in optical system of holographic memory and present a technique for reducing the fixed pattern noise from reproduced data pages.
