A channel data retrieval scheme for page-based holographic data storage has been developed. It includes several signal-processing blocks for retrieving data reliably under noisy condition; namely; a frame grabber for capturing data adaptively in a rotating disk; a mark detector for tracing the data location; an equalizer for compensating interference; a two-dimensional modulation decoder for suppressing errors; and a three-dimensional error correction decoder for correcting errors generated by the holographic storage channel. The proposed scheme has been implemented with a field-programmable gate array chip and applied to actual data retrieval from holographic data storage. With the proposed channel data retrieval hardware; the user video data is successfully reconstructed from the holographic disk; which contains video data as holograms. © 2006 The Japan Society of Applied Physics;
