摘要:
A hologram duplication method is disclosed which makes it easy to duplicate a large number of holograms from a volume-recorded hologram, particularly from a hologram recorded in a recording medium of the disk type or the card type. N card type master recording media are prepared, and data pages are individually recorded on the N disk type master recording media without being multiplexed by changing the angle of a reference light beam among the N disk type master recording media. Thereafter, the data page recorded on each of the disk type master recording media is recorded on a common disk type duplication recording medium so that the data pages are N-multiplex recorded finally on the disk type duplication recording medium.
