We present wavelength-multiplexed holographic recording forhigh-density, high-speed data storage using reflection geometry with ahigh-sensitivity cerium-doped strontium barium niobate single-crystalstructure and second-harmonic generated light from a compact andconvenient wavelength-tunable laser diode. We have recorded andreconstructed wavelength-multiplexed holograms by using wavelengths0.053-nm apart. The theoretical wavelength selectivity of thehologram with the linewidth of the light source taken intoconsideration agrees well with the experimental wavelength selectivity.
