Paper Abstract

For holographic memory, write-once type data recording has been studied by using photopolymer material. By considering the fact that the development of optical disks has been undertaken for both the ROM type and recordable type, there seems to exist a need to develop a ROM type disk for holographic memory. For this ROM type disk, the desired manufacturing method will be the one used for DVD disk production. Also, from the view point of data transfer speed, the function to reproduce data from a disk continuously rotating at high speed seems necessary. This paper describes a phase code multiplexed ROM type holographic memory using computer generated hologram as recorded data.
