The near stoichiometric Mg:Fe:LiNbO_3(Mg:Fe:SLN) crystal has been prepared by using the top seed solution method with K_2O as fluxing medium. The ultraviolet absorption spectrum and response time of Mg:Fe:SLN has been tested and compared with the congruent Fe:LiNbO_3′s (Fe:CLN) crystal.The results indicated that Mg:Fe:SLN is much more suitable for holographic storage medium than Fe:CLN.Against the high inherent primary error code rate in the holographic storage,QR (Quick Response Code) coding technique was employed to encode the raw data,thus the pressure of system design and component quality and other aspects have been relieved.The volume holographic data storage system has been constructed by using Mg:Fe:SLN crystal as the storage medium. The reconfigureable data can be successfully replayed by applying the QR encoding and decoding technique to the multimedia data holographic storage including video and audio information.
