Abstract

PURPOSE:To miniaturize the titled device by arraying plural electromagnetic driving means for driving an objective lens in respectively different directions, i.e. the optical axis direction of the objective lens, the tracking direction of a recording medium and directions rectangular to the optical axis direction and the track direction. CONSTITUTION:Plural electromagnetic driving means 42, 43 for driving the objective lens 21 are arranged in the optical axis direction of the objective lens 21, the track direction of the recording medium and directions different from the tracking direction. In case of projecting optical beams 44 in parallel with the recording medium and obliquely to the track direction, reflecting the beams 45 by a mirror 44 and making the reflected beams vertically incident upon the objective lens 21, the optical path of the optical beams 45 made incident upon the mirror 44 can be set up in the vicinity of the recording medium without being disturbed by the means 42, 43 and the mirror 4 can be also effectively arranged in the vicinity of the objective lens 21. Consequently, the size of the device in the optical axis direction can be reduced and the device can be miniaturized.
