摘要：
A holographic memory device is described which records and reproduces binary image data by irradiating a holographic recording medium with signal light and reference light. The holographic memory device includes a system for aligning polarization of the signal light and reference light on the holographic recording medium by guiding the signal light and the reference light to be coaxially opposed. The holographic memory device further includes a random-phase modulation multiplex recorder and spatial-shift multiplex recorder that, together with the system for aligning polarization, significantly enhances recording density and improves recording capacity.
