Abstract

Multiplexing characteristics of a dc-removed coaxial holographic storage system were evaluated for what is believed to be the first time. Our dc-removed coaxial system achieved 3.5 times higher raw data density than a conventional coaxial system that involved dc recording. The increase of the data density was due not only to less $M/\#$ consumption but also to the effects of signal amplification and noise reduction by use of the positive and negative images reconstructed from the same holograms.
