| Outline of Final Research Achievements |
In the hologram memory, we have developed a three-dimensional cross-shift multiplex recording system using a spherical reference light. By combining the method both writing technology for the shift multiplexing in the medium plane with a cross-shift angle 10 degree and the overwriting technology for the shift multiplxing by the medium tilt angle about 5, which is formed by the photopolymer material 5 inch disk medium, the information amount of data about 2TB can be recorded in this 5 inch disk. Symbol error rate and signal to noise ratio in the entire disc surface can be in the practical level. Recording speed of data have achieved 100Mb / s. For further large-capacity in the future, the amplitude multi-level recording and reproduction will be studied.
