| Abstract(in English) | Abstract: The hologram memory is expected as one of the high recording density technology. We have studied magnetic garnet films ashologram material without light shielding. The hologram recorded in magnetic material by volumetric thermomagnetic writing is reconstructed as phase hologram from volumetric distribution of the magnetization. Increase of diffraction efficiency is important to achieve high recording density by volumetric magnetic hologram. In this paper, we compared computer simulation with experiments to find a better condition for high diffraction efficiency. The use of short pulse laser of 50 psec for recording was found effective to achieve high diffraction efficiency though the suppression of heat diffusio |
