Holographic memory is a promising next-generation optical memory that has a higher recording density and a higher transfer rate than other types of memory. In holographic memory, magnetic garnet films can serve as rewritable holographic memory media by use of magneto-optical effect. We have now demonstrated that a magnetic hologram can be recorded volumetrically in a ferromagnetic garnet film and that the signal image can be reconstructed from it for the first time. In addition, multiplicity of the magnetic hologram was also confirmed; the image could be reconstructed from a spot overlapped by other spots.
全息存储器是一种很有前途的下一代光学存储器，它具有比其他类型存储器更高的记录密度和更高的传输速率。在全息存储器中，磁性石榴石薄膜可通过磁光效应用作可重写全息存储介质。我们现已证明，磁性全息图可在铁磁石榴石薄膜中进行体记录，并且首次能够从中重建信号图像。此外，还证实了磁性全息图的多重性；图像可从与其他光斑重叠的光斑处重建。
