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 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.
