    • According to one embodiment, an optical disk device includes types of semiconductor laser diodes configured to emit laser light of different wavelengths, an output control circuit configured to control light output of each semiconductor laser diode, and a composite power source configured to generate voltages required for driving the types of semiconductor laser diodes and operating the output control circuit from a single power source voltage and to selectively output the generated voltages. The composite power source includes an input port to input an external control signal at a time of voltage selection and is configured to change the output voltage stepwise in response to the control signal.
    • 根据一个实施例,光盘装置包括配置为发射不同波长的激光的半导体激光二极管的类型,被配置为控制每个半导体激光二极管的光输出的输出控制电路和被配置为产生 驱动类型的半导体激光二极管,并从单个电源电压操作输出控制电路并选择性地输出所产生的电压。 复合电源包括在电压选择时输入外部控制信号的输入端口,并且被配置为响应于控制信号逐步改变输出电压。
