- 論文の詳細を見る
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.
