| Outline of Final Research Achievements |
We investigated the recording and reconstruction method using the collinear interferometry. We found that clear reconstructed images were obtained at a position shifted slightly from the focal point and that errorless recording and reconstruction was performed. In addition, by applying magnetic assist recording method, much clear reconstructed images were obtained, and errorless recording and reconstruction was attained even with small writing energy. As magnetic recording media for volumetric recording of magnetic holograms, we proposed multilayered media inserting heat sink layers by simulation and experiment. As a result, it was revealed that a diffraction efficiency higher than that of the conventional single layer film could be obtained, and errorless recording and reconstruction by the collinear method was possible even in the multilayered media in which the recording layers are discretely existed.
