The movable portion has a first optical path for irradiating the beam from the irradiation optical system onto the recording medium and a second optical path for guiding the beam from the recording medium to the detection optical system. The first optical path and the second optical path are formed as partly different paths. A beam separator for separating the beam from the irradiation optical system into a plurality of beams is set in the specific path only for the first optical system.

    摘要: Different tracks on an optical information recording medium are irradiated with first and second light spots for auto-tracking. The light of the first light spot via the recording medium is detected to produce a first detection signal and light of the second light spot via the recording medium is also detected to produce a second detection signal. On the basis of a difference between the first and second detection signals, a signal used for performing tracking control of a third light spot for recording or reproducing information is generated. When recording or reproduction of information is effected on/from one of a first recording medium having a track pitch P.sub.1 and a second recording medium having a track pitch P.sub.2 and the first and second recording media satisfy a relation P.sub.1 -P.sub.2 =d (d is the width of the tracking track) while executing auto-tracking control, a relationship of a direction of movement of the third light spot in a track intersecting direction with respect to a polarity of a signal obtained by subtracting the second detection signal from the first detection signal between the first and second recording media is inverted.
