  • Patent number: 8279736
    Abstract: The present invention discloses a multilevel recording method and system thereof. The multilevel recording method applied to a recording media comprises the following steps. At First, a plurality of beams are provided to a recording layer of the recording media, and the recording layer has a first structure and a second structure. Then, a first polarized reflected light of the first structure and a second polarized reflected light of the second structure are detected by a detecting unit. Then, a corresponding table is stored by a storing unit. The corresponding table comprises a relationship between the different angle of the polarized reflected light and a level of multilevel recording. Finally, the processing unit looks up the corresponding table to process multilevel recording.
