ABSTRACT:
The present invention relates to an optical recording apparatus, which converts a one-dimensional signal beam into a two-dimensional signal beam using a scanning mirror at the time of recording data on a holographic recording medium, etc., thus greatly reducing required manufacturing processes when manufacturing a spatial light modulator. The optical recording apparatus includes a light generation and radiation means for generating beams, and dispersing and radiating the beams in two directions. A reference beam radiation means converts radiation angles of reference beams and radiates the reference beams having different angles onto a recording medium. A one-dimensional signal beam generation means diffracts and spatially modulates the beams incident from the light generation and radiation means to generate a one-dimensional signal beam and radiates the one-dimensional signal beam. A two-dimensional signal beam radiation means reflects the one-dimensional signal beam in two directions on the same horizontal plane and radiates a two-dimensional signal beam onto the recording medium.
