Abstract:
    A 3D disc holographic storage method is separation orbit storage which works as overlapping partially all holograms on adjacent orbits, recording and reading out all holograms without adjusting angle of reference light and illuminating light, using disc rotation to finalize addressing of hologram in the same orbit and using read - write optical system and disc flat motion to finalize addressing of hologram on different orbit, applying separation orbit heat - fixing as storing method. The 3D disc holographic storage system is also disclosed.
