| 英文摘要 | An optical pick-up is arranged to detect information recorded on an optical disk by causing laser light projected onto and reflected from a signal surface of the optical disk disposed within an optical system and the laser light is received by a light receiving element provided in the optical system. The optical pick-up is mounted with a laser diode unit which includes a metallic substrate, a laser diode, a photo-diode, a current feeding lead portion to the laser diode and a current output lead portion which forms the photo-diode, respectively disposed at one side face in the direction of thickness of the metallic substrate for emitting the laser light. The laser diode unit is positioned and fixed at a predetermined position of the optical system through a mounting member. The mounting of the laser diode unit includes setting the other side face in the direction of thickness of the substrate and the mounting member in a desired positional relation for contact with each other as a result, a plurality of contact places therebetween may be simultaneously welded by laser light for combining the laser diode unit and the optical pick-up into one unit. |
