Paper Abstract

Microholographic recording with multiplexing of ten bits has been experimentally demonstrated by the combination of wavelength multiplexing and angle multiplexing. The wavelength of the beams has been varied in two states and the incident angle of the beams on the recording medium has been varied in five states. New coding methods to which these technologies are applied have also been proposed. They lead to the effective use of the dynamic range of the recording medium. It is expected that terabyte-order recording capacity would be achieved by further combining these technologies with three-dimensional shift multiplexing technologies.
