Patent attributes
A hologram recording apparatus is provided, including: 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 including a first optical element which splits the signal beam into a plurality of sub signal beams and deflects the plurality of sub signal beams in different directions. The signal beam forming unit further directs the plurality of sub signal beams onto a hologram recording medium. The recording apparatus also includes a reference beam forming unit which directs the reference onto a location on the hologram recording medium which overlaps with locations on the hologram recording medium on which the plurality of sub signal beams are incident.
