| 摘要 |
This invention provides a hologram recording apparatus for recording an interference fringe, generated by interference of a first light beam subjected to spatial light modulation by recording data with a second light beam, in a recording area of a hologram recording medium, the hologram recording apparatus including: a random phase body for randomizing the wave front of the second light beam, and a multiplex recording control unit for recording the interference fringe of the first light beam and the second light beam in the same recording area of the hologram recording medium each time the random phase body is rotated.
