description A holographic information recording and/or reproducing apparatus, including a light source to emit light; a polarization forming optical system to form a polarized signal beam and a polarized reference beam from the light emitted from the light source, wherein the polarized signal beam and the polarized reference beam are incident on a holographic information storage medium through an identical surface; a focusing optical system to focus the polarized signal beam and the polarized reference beam onto in the holographic information storage medium so that information is recorded by an interference pattern; and an adjustment optical system to set the focal positions of the polarized signal beam and the polarized reference beam, and to adjust a difference between a path of the polarized signal beam and a path of the polarized reference beam.
