ABSTRACT:
A multi-beam optical head includes a plurality of light sources for emitting a plurality of light beams. An optical system for irradiating the light beams onto the recording surface of a recording medium is included and receives the light beams reflected from the recording medium. The optical system includes a reflecting mirror for directing the light beams emitted from the light sources toward the recording medium; a photodetector for detecting the light beams received by the optical system and for generating electric signals based on the detected light beams; and rotational controller for controlling the reflecting mirror to rotate around an axis which is perpendicular to the recording surface by an amount determined based on the electric signals. The reflecting mirror positions the light beams on tracks on the recording surface of the recording medium. The tracks are tracks on which information is recorded from which the information is reproduced.
