An optical recording and reproducing apparatus for optically recording and reproducing information on and from a disk comprises: a light source for generating a parallel beam; a movable optical system adapted to condense the parallel beam from the light source on the disk, to split the beam reflected by the disk into a first and a second beam, to spatially invert the second beam, and to move in the radial direction of the disk; a first split-beam detecting device having two light receiving surfaces which respectively receive the first beam; a second split-beam detecting device having two light receiving surfaces which respectively receive the second beam inverted in the movable optical system; and a control device adapted to effect tracking control by moving the movable optical system in the radial direction of the disk in accordance with respective detection signals output from the first and second split-beam detecting devices.
