    摘要: A holographic recording method includes the following steps: irradiating an optical recording medium with a coherent reference beam and a coherent information beam to produce a hologram in the optical recording medium while irradiating the optical recording medium with an incoherent pretreatment beam to consume a polymerization inhibitor; irradiating the hologram with the reference beam to extract a reproduction beam while stopping irradiating the optical recording medium with the reference beam; sensing the signal beam with an image pick-up unit to detect an intensity of the signal beam; and calculating a bit error rate with a control unit to irradiate the hologram with the information beam if the bit error rate is larger than a prescribed value, or to stop irradiating the optical recording medium with the reference beam, the information beam and the pretreatment beam if the bit error rate is smaller than the prescribed value.
