Method for polarization data recording/retrieval on luminescent optical data carriers |
摘要 |
A method is proposed for data recording/retrieval on two- or three-dimensial luminescent optical data carriers for WORM and WER optical disks, cards and the like. In said method, polarization-sensitive photoluminescent materials are used as media for optical data carriers in order to improve effective sensitivity in data recording, to increase recording velocity and to raise the signal-to-noise ratio in data reading. Bit-by-bit or page-by-page recording of information is performed by means of polarized radiation in a one- or two-photon absorbtion mode. Bit-by-bit or page-by-page reading is realized through detecting the availability or absence of luminescence anisotropy of information marks (pits) in one-photon absorption of reading radiation. Photosensitive components for polarization-sensitive luminescent materials are chosen from those classes of compounds that show strong absorption and luminescence anisotropy in the original and/or photoinduced states. |
