Method for optical data recording

摘要

The invention concerns a method for optical recording of data on a photosensitive storage medium, characterized in that the data are encoded according to different possible states for the various components of a non-linear susceptibility tensor of the photosensitive medium and it consists in irradiating simultaneously at least a point of said support with write beams whereof the polarization is controlled for optical recording of a given non-linear susceptibility tensor on the photosensitive medium.
