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.
