A series of LiNbO3:Hf:Ce:Cu crystals with various level of Hf doping were prepared using the Cz equipment with a resistance furnace. The crystal storage properties with optical damage resistance ability, sensitivity and dynamic range were measured by means of two-beam coupling light path. The defect structure is also discussed, accounting for the optical damage resistance. Based on optimal one of these crystals as storage medium, one thousand of holograms were recorded in a public coherent volume of 0.073 cm3. The result shows that storage density arrives10.7Gbits/cm3 and the crystal has potential application in the future high density storage..
