摘要： An optical pickup device for reproducing information signals recorded on a multilayer optical disk provided with a plurality of information signal layers in which desired information signals are recorded. The optical pickup device is provided with a light source which emits a light beam, optical means which splits the light beam into a main beam, a first side beam, and a second side beam and irradiates the optical disk with a three beams, a light receiving section for the main beam which receives the main beam reflected from the optical disk, light receiving sections for the side beams which respectively receive the first and second side beams reflected from the optical disk, and means which outputs light intensity detection signals corresponding to the intensities of the three light beams. The light receiving sections for first and second side beams are located at prescribed intervals from the light receiving section for main beam, so that the two side beams do not interfere with the main beam reflected from a non-focused information signal layer of the disk. The information signals recorded on the information signal layer can be accurately reproduced without any influence of the reflected light from the non-focused information signal layer.
