ABSTRACT:
An optical information storage apparatus is constructed to include a light source, a polarization beam splitter reflecting light emitted from the light source and irradiating a reflected light on a recording surface of a recording medium, and an optical element, made of an optically transparent material, having an input surface to which light reflected by the recording surface and transmitted through the polarization beam splitter is input, and an output surface from which light is output. The optical element is inclined within a plane which is perpendicular to a light incident surface of the polarization beam splitter and includes an optical axis along which light travels. In addition, the input surface and the output surface of the optical element are parallel to each other.
