    • This invention relates to a protect circuit of an optical disk drive, which comprises a discharge circuit being at least connected to a first DC voltage and a ground terminal, wherein the first DC voltage and ground terminal are electrically connected to a power socket of the optical disk drive, and the discharge circuit is used to supply the electric power for the operation of the optical disk drive. If the first DC voltage and ground terminal are unplugged abnormally from the power socket, the first DC voltage and the ground terminal are connected immediately to discharge the remaining electricity of the first DC voltage in the optical disk drive.
    • 本发明涉及光盘驱动器的保护电路,其包括至少连接到第一直流电压和接地端子的放电电路,其中第一直流电压和接地端子电连接到光学器件的电源插座 磁盘驱动器,并且放电电路用于为光盘驱动器的操作提供电力。 如果第一个直流电压和接地端子从电源插座异常拔出,第一个直流电压和接地端子立即连接,以释放光盘驱动器中第一个直流电压的剩余电量。
