<p>A hologram recording device (100) includes parameter setting means (19), shifting means (20), and control means (18). The parameter setting means (19) modifies parameters for multiplex recording such as a recording angle and a focal depth relating to at least one of signal light (L3) and reference light (L2) and can fix the parameters. The shifting means (20) relatively shifts the focusing position of the signal light and the reference light with respect to a hologram recording medium in the direction along the recording surface. The control means (18) performs control so that the last multiplex recording parameter used for recording at the m-th focusing position is used as the first multiplex recording parameter for recording at the m+1-th focusing position.</p> |
