ツプ装置。[Claims for Utility Model Registration] An optical pickup system having a light source that emits a laser beam used to reproduce information signals recorded on a disk; a beam splitter that receives a portion of the laser beam and irradiates the laser beam onto the information recording surface of the disk on which the information signal is recorded, and is capable of adjusting an arbitrary angle; The disk tilt detection system includes a two-part sensor that receives reflected light from the information recording surface, and a collimator lens that maintains a constant distance from the information recording surface of the disk. By adjusting the angle of the beam splitter, the optical axis of the laser beam irradiated from the optical pickup system onto the information recording surface of the disk and the optical axis of the laser beam irradiated from the disk tilt detection system onto the information recording surface of the disk can be adjusted. An optical pickup device characterized by aligning the optical axis of a laser beam.
