METHOD OF RECORDING HOLOGRAPHIC INFORMATION AND APPARATUS OF RECORDING/REPRODUCING HOLOGRAPHIC INFORMATION

摘要

PURPOSE: A holographic information recording method and a holographic information recording/reproducing apparatus are provided to enhance recording precision by lowering spherical aberration to when the depth and the light of a following information layer reach the formed following information layer. CONSTITUTION: A holographic information recording method comprises the following steps. A hologram mark is recorded on the holographic recording layer(260) of a holographic information storage medium to form an information layer. Light is illuminated and fixed to the information layer on which the hologram mark is recorded. In the holographic recording layer, a plurality of information layers on which the hologram mark is recorded are formed in a longitudinal direction. One information layer is formed by recording the hologram mark. After illuminating and fixing light to the information layer, a hologram mark recording for a following information layer formation is performed and the formation of a plurality of information layers and the fixing of each information layer are accomplished.
