Abstract
We propose a simultaneous dual-page reproduction for holographic data storage (HDS) with high-efficiency and high-speed data reproduction by reusing a transmitted reference beam that passes through a recording medium after data reconstruction. The transmitted reference beam enters the recording medium at a different incident angle to reproduce different data pages; thus, this technology can double data-transfer rates without increasing the laser's output power or preparing another laser source. In the experiment, neighboring angle-multiplexed two data pages were simultaneously reconstructed and a data transfer rate of 1.0 Gbps was obtained.
