Abstract
Appropriate recording with respect to a hologram recording medium is to be realized. After a region recording process of arranging holograms in which information is recorded at a predetermined interval in a first predetermined region of the hologram recording medium, and before a post-curing with respect to the first predetermined region is performed, signal light and reference light are applied onto a region different from the first predetermined region to perform information recording.
Claims18
A hologram recording device that irradiates a hologram recording medium with signal light and reference light to perform information recording, comprising:
- recording position change means for changing an irradiation position of the signal light and the reference light to change a recording position on the hologram recording medium;
- region recording means for performing a region recording process of arranging holograms in which information is recorded at a predetermined interval in a predetermined region on the hologram recording medium by changing the recording position using the recording position change means and by controlling the irradiation of the signal light and the reference light;
- and
- post-curing means for performing a post-curing process of irradiating a region where the information recording is completed with a predetermined light beam,
- wherein within a time from the time when the region recording means performs a first region recording process with respect to a first predetermined region of the hologram recording medium to the time when the post-curing means performs the post-curing process with respect to the first predetermined region, the signal light and the reference light are applied onto a region different from the first predetermined region to perform the information recording.

- wherein within a time from the time when the region recording means performs a first region recording process with respect to a first predetermined region of the hologram recording medium to the time when the post-curing means performs the post-curing process with respect to the first predetermined region, the region recording process with respect to a region different from the first predetermined region is performed at least once.
A hologram recording method for irradiating a hologram recording medium with signal light and reference light to perform information recording, comprising the steps of:
- performing hologram recording while controlling an irradiation position and an irradiation time of the signal light and the reference light and arranging holograms in which information is recorded at a predetermined interval in a first predetermined region of the hologram recording medium;
- irradiating a region different from the first predetermined region with the signal light and the reference light to record the information;
- and
- performing a post-curing process of irradiating the first predetermined region with a predetermined light beam.
