HOLOGRAPHIC DATA STORAGE MEDIUM, AND APPARATUS AND METHOD FOR RECORDING/REPRODUCING HOLOGRAPHIC DATA ON/FROM THE SAME

摘要

A storage medium of holographic information and apparatus and method for recording and playing holographic information using the same are provided to have and efficiently distinguish a plurality of information layers. A holographic information storage medium comprises: a substrate; a holographic recording layer(120) on the substrate; and a cover layer(190) which covers the holographic recording layer. The holographic recording layer forms different layers based on the depth direction and comprises an information recording layer and layer discriminating area.
