Hologram recording medium, and recording apparatus and reproducing apparatus for the same
摘要:
A hologram recording medium, and a recording apparatus and a reproducing apparatus for the same, by which scattered beam noise is minimized and recording capacity is increased using spatial separation and polarization separation in an optical system where a reference beam and an object beam travel through the same optical path. The provided hologram recording medium includes a recording layer into which an object beam and a reference beam are radiated to record data of the object beam as interference fringes, and first and second phase difference layers arranged above and below the recording layer, respectively, to convert the polarization of an incident beam.
