ABSTRACT:
In holographic recording by the angle multiplexing method, in order to allow a signal beam and a reference beam to sufficiently overlap with each other in a storage medium to decrease as much as possible a wastefully exposed region, which does not contribute to a signal recording, an optical pickup apparatus having a function which can control, for example, a size or a position of an aperture of the reference beam is used. An optical information reproducing apparatus or an optical information recording and reproducing apparatus using the optical pickup apparatus is used.
