ABSTRACT:
Provided are optical information processing apparatus and method. In the optical information processing apparatus and method, when the recording regions in which optical information is recorded in an angular multiplexing scheme overlap with each other, a recording angle and a recording position for optical information is adjusted so as to improve reproducing efficiency of readout beams reproduced from the overlap recording regions, so that heights of “null” for diffraction energy reproduced from the recording regions and overlap recording regions can be lowered. Accordingly, it is possible to reduce crosstalk noise during the recording and producing of the optical information and to improve optical information recording quality and reproducing efficiency.
