Abstract
A light information recording/reproducing apparatus can improve the optical efficiency of an optical system at the time of reproduction to thereby improve the reproduction transfer rate. An optical element (for example, an optical isolator), which removes a return light beam of a light beam, is arranged such that the light beam passes through the optical element at the time of recording information in an optical information recording medium and such that the light beam does not pass through the optical element at the time of reproducing information from the optical information recording medium.
