    • An optical pickup according to the present invention includes an integrated circuit element (LDD) 5 for driving first, second, and third semiconductor lasers 3, 4, and 5. The LDD 50 is shaped so as to have a rectangular principal face surrounded by one side, with a plurality of input/output pins being arranged along each side. The plurality of input/output pins include a first pin group connected to a blue-violet laser 5 whose oscillation wavelength is the shortest, a second pin group connected to a red laser 4, and a third pin group connected to an infrared laser 3. The wiring structure of the optical pickup includes a first transmission line 41 for connecting the first pin group to the blue-violet laser 5, a second transmission line 33 for connecting the second pin group to the red laser 4, and a third transmission line 31 for connecting the third pin group to the infrared laser 3, where the first transmission line 41 is shorter than both the second and third transmission lines 31 and 33. Of the rectangular principal face of the LDD 50, the side along which the first pin group is provided is orthogonal to the side along which the second pin group is provided or to the side along which the third pin group is provided.
    • 根据本发明的光拾取器包括用于驱动第一,第二和第三半导体激光器3,4和5的集成电路元件(LDD)5。LDD 50被成形为具有被一个包围的矩形主面 其中沿着每一侧布置有多个输入/输出引脚。 多个输入/输出引脚包括连接到振荡波长最短的蓝紫色激光器5的第一引脚组,连接到红色激光器4的第二引脚组和连接到红外激光器3的第三引脚组。 光拾取器的布线结构包括用于将第一引线组连接到蓝紫激光器5的第一传输线41,用于将第二引脚组连接到红色激光器4的第二传输线33和第三传输线31 用于将第三引脚组连接到红外激光器3,其中第一传输线41比第二传输线31和第三传输线33短。在LDD 50的矩形主面中,第一引脚组 被设置为与设置有第二引脚组的一侧或与设置第三引脚组的一侧正交。
