Holographic Record Carrier |
摘要 |
A holographic record carrier is capable of recording or reproducing information by irradiating light. The holographic record carrier is comprised of a holographic recording layer for storing an optical interference pattern produced by a signal light component of a coherent reference light and a signal light as a diffraction grating therein; a reflective layer stacked on the holographic recording layer in the opposite side of the light incidence side; and a plurality of non-reflective regions arranged on the reflective layer in the same interval as the record-interval of the diffraction grating.
