(EN) Provided are a holographic data storage medium and an apparatus and method for recording/reproducing holographic data using the same. The holographic data storage medium includes: a substrate; a holographic recording layer disposed on the substrate; and a cover layer covering the holographic recording layer. The holographic recording layer includes: a data recording region including a plurality of data layers to which data is recorded, the data recording region in which interference fringes due to first and second beams are formed in different data layers in a depthwise direction; and a layer discrimination region for providing discrimination between the data layers.
(ZH) 提供了一种全息数据存储介质以及利用其记录/再现全息数据方法和设备。全息数据存储介质包括:基底;全息记录层,设置在基底上;覆盖层,覆盖全息记录层。全息记录层包括:数据记录区,包括记录数据的多个数据层,在数据记录区中,由第一光束和第二光束导致的干涉条纹形成在沿深度方向的不同数据层中;层区分区,用于提供数据层之间的区分。
