    • A first overcurrent detecting circuit outputs a first time-up signal when a time period, in which an electric current flowing into the wire harness is greater than the first threshold, reaches a first duration time, which corresponds to a first threshold. A second overcurrent detecting circuit outputs a second time-up signal when a time period, in which an electric current flowing into the wire harness is greater than the second threshold, reaches a second duration time, which corresponds to a second threshold. The second threshold is less than the first threshold. The second duration time is longer than the first duration time. A determination circuit determines that an overcurrent flows into the wire harness and cause a control circuit to deactivate the switching element when inputting at least one of the first and second time-up signals.

    • In write power adjustment for an optical disc having a plurality of information storage layers, data of trial writing is varied by the influence of layers other than a target layer. It is difficult, therefore, to determine optimal write power. A modulation M[m] is obtained from a reproduction signal amplitude of a signal subjected to the trial writing performed with use of write powers Pw[m] (m being an integer) of a plurality of kinds. At least an optimum write power intercept Pint_opt is determined by fitting a relation between the Pw[m] and the M[m] by a modulation characteristic formula M=Masy×(1−(Pint−Pasy)/(Pw−Pasy)) having an asymptotic modulation Masy, a write power intercept Pint, and an asymptotic write power Pasy as parameters. Approximation accuracy by the fitting and/or quality of the trial writing signal are evaluated with use of at least the M[m], the modulation characteristic formula, and the Pint_opt. An optimum write power Pw_opt is calculated by performing a specified operation at least with use of the Pint_opt.
    • 在具有多个信息存储层的光盘的写入功率调整中,试写的数据由目标层以外的层的影响而变化。 因此,很难确定最佳写入功率。 通过使用多种写入功率Pw [m](m为整数)进行试写的信号的再现信号振幅,获得调制M [m]。 通过用调制特性公式M = Masy×(1-(Pint-Pasy)/(Pw-Pasy))拟合Pw [m]和M [m]之间的关系来确定至少最佳写功率截止Pint_opt 具有渐近调制Masy,写功率截取Pint,渐近写功率Pasy作为参数。 通过使用至少M [m],调制特性公式和Pint_opt来评估试写信号的拟合和/或质量的近似精度。 至少通过使用Pint_opt执行指定的操作来计算最佳写入功率Pw_opt。
