ABSTRACT:
An optical pickup device operates to irradiate a disk with an optical beam from a light source by an objective lens and to detect the beam reflected from the disk by a light receiving element. A frame is provided for said device having an optical element fixed therein. The frame is formed with a press-fit hole into which the light source is press-fit and fixed so as to adjust the press-fit depth, thereby adjusting alignment between the optical pickup device and the disk.
