ABSTRACT:
At least two light sources are provided for an optical information recording/reproducing apparatus. The light sources emit a recording light beam and a reproducing light beam to form a recording light spot and a reproducing light spot on a recording medium. A wedge glass plate is interposed in the optical path of the beams. The wedge glass plate is rotated to adjust one or both positions of the recording and reproducing light spots formed on the recording medium.
