ABSTRACT:
A holographic memory system includes a spatial light modulator having multiple modulators for spatially modulating at least a portion of a light beam emitted from a light source and rendering it as an information light beam, and a light sensing device for reading the information light beam taken out of a recording medium. The spatial light modulator and the light sensing device are integrally formed on the same substrate.
