Claim Text:
1. A hologram recording apparatus comprising: a coherent light source; a beam splitter which splits a beam emitted from the coherent light source into a signal beam and a reference beam; a signal beam forming unit comprising a first optical element which splits the signal beam into a plurality of sub signal beams and deflects each of the plurality of sub signal beams in a different direction, wherein the signal beam forming unit further directs the plurality of sub signal beams onto a plurality of different locations, respectively, on a hologram recording medium, such that each of the plurality of sub signal beams is incident on the hologram recording medium at the same angle; and a reference beam forming unit which directs the reference beam onto a location on the hologram recording medium which overlaps with the plurality of different locations on the hologram recording medium on which the plurality of sub signal beams are incident; wherein the overlapping of the plurality of sub signal beams and the reference beam on the hologram recording medium simultaneously records a plurality of hogels at the plurality of different locations on the hologram recording medium.
