摘要： PROBLEM TO BE SOLVED: To enable the reduction of a size, weight and cost of an optical pickup and to improve the detection accuracy of a tracking error signal with an optical disk device which can read and/or record data out of and/or to a plurality of kinds of optical disks varying in specifications. SOLUTION: One optical element formed with diffraction gratings for diffracting first and second laser beams respectively varying in wavelengths on both surfaces is used and the first and second laser beams outputted from two semiconductor lasers are converged by utilizing the same optical system. The directions of the grating grooves of the respective diffraction gratings are so set as to reverse the direction where the straight line LD connecting each diffracted light +D1, D0 and -D1 of the first laser beam intersects with a track 40 on the optical disk with respect to the direction where the straight line LC connecting each diffracted light +C1, C0 and -C1 of the second laser beam intersects with the track 40 on the optical disk on the disk.
