DATA PROCESSING METHOD FOR HOLOGRAPHIC OPTICAL INFORMATION RECODING EQUIPMENT AND DATA PROCESSING METHOD OF HOLOGRAPHIC OPTICAL INFORMATION REPRODUCING EQUIPMENT

摘要

A data processing method for a holographic optical information recording device and a data processing method of a holographic optical information reproducing device are provided to be capable of effectively distributing data errors when the data errors are generated owing to a 2-dimensional burst error, thereby easily and perfectly restoring damaged data. Data of data page unit are divided into plural data sets(S11). The data of the data sets are mixed through the first interleaving process, respectively(S12). The data of the data page unit formed by collecting the data of each data set whose first interleaving process is finished are mixed through the second interleaving process(S13). The data whose second interleaving process is finished are loaded to a space light modulator(S14).
