ABSTRACT:
A unit according to the present invention includes a substrate and an IC chip used for driving a light-emitting device. A relay terminal is provided at a region spaced from peripheral areas of the substrate so as to connect the light-emitting device with the IC chip. The relay terminal is connected with a corresponding terminal of the IC chip via a connecting channel such as wire-bonding. The light-emitting device is supported by the substrate such that a terminal of the light-emitting device is electrically connected with the relay terminal. A length of a wiring line between the light-emitting device for an optical pick-up and the unit used for driving the light-emitting device is decreased.
