Filed: 2000-04-03
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of the noise due to the external light or the noise caused by an optical recording medium and to realize the multi-valued and high density recording. SOLUTION: A light wave 2 for noise cancellation has a constant light intensity with a polarization of 0 deg.. A signal light 1 has a light intensity with polarization of 90 deg. multi-valued in accordance with a value s of multi-valued data. The signal light 1 and the light wave 2 for noise cancellation are combined, and a light wave 3 prepared by the combination is recorded on the optical recording medium as a recording light. Reproducing light having the same wave front as that of the recording light 3 is read out from the optical recording medium at the reading time, and the polarization components of the reproducing light orthogonally crossed each other are separated to figure out the difference of light intensity between two polarization components. By this procedure, the noise is cancelled, and a value s of the recorded multi-valued data is read out without error.  In the case the coherent noise caused by the optical recording medium is dominative, the reproducing light is made to pass through a polarization element, and the polarization components in the reproducing light orthogonally crossed each other are brought to interference with the phase difference π, then the value s of the multi-valued data is read out from the intensity of the light transmitted through the polarization element.
