Light-emitting elements 6a-6c detect signal from change in light which is irradiated to the rear of a chip due to returning light. A waveguide channel 7 of a light guide 8 separates each light which is irradiated to the rear, thus leading it toward each light-receiving element. Output of light which is irradiated to the rear of the laser chip increases along with the returning light rate so that the level of potential of light output which is irradiated to the rear of the chip 1b where the laser light 3b which is centered onto a recording track 9 becomes a returning light is judged, thus detecting the direction and amount of track deviation.
