摘要： A holographic storage medium includes a substrate; a cover layer to receive a first circular polarization beam having a first polarization direction and a second circular polarization beam having a second polarization direction orthogonal to the first polarization direction; a polarization beam splitting/reflective layer disposed between the substrate and the cover layer to reflect the first beam while maintaining the first polarization direction of the first beam, and to transmit the second beam; and a holographic recording layer disposed between the polarization beam splitting/reflective layer and the cover layer to record information as an interference pattern formed in the holographic layer by the first beam reflected by the polarization beam splitting/reflective layer and the second beam received by the cover layer.

摘要： A method and apparatus for improving quality of a signal reproduced from a holographic storage medium in which a hologram is recorded by interference between a signal beam and a reference beam. The signal-quality improving method includes determining a page crosstalk value, which is caused in a page that is to be reproduced from the holographic storage medium by an adjacent page to the page that is to be reproduced, on the basis of on-pixel crosstalk values caused by a plurality of on-pixels of the adjacent page; and removing the determined page crosstalk value from a reproduced signal of the page that is to be reproduced. Since an interpage crosstalk that occurs when multiplexing recording in the holographic storage medium is calculated, and is removed from a reproduced signal, the quality of the reproduced signal can be improved.
