PROBLEM TO BE SOLVED: To make actual information amount density during recording, reproduction or measurement closer to potential information amount density than in the conventional practice.;SOLUTION: Phase modulation light A' generated by performing spatial phase modulation processing is irradiated to a recording medium 13, and the same phase modulation processing as the spatial phase modulation processing is applied to complex amplitude of outgoing light emitted from the recording medium 13, or the outgoing light emitted from the recording medium 13.;COPYRIGHT: (C)2014,JPO&INPIT
