    • In the information recording apparatus, by driving the light source by the pulse signal corresponding to the recording signal, the laser pulse corresponding to the recording signal is irradiated onto the recording medium. The recording signal has the mark period to form the recording mark, and the space period in which the recording mark is not formed. In the mark period, the output level of the laser pulse changes between the normal level and the writing level, thereby, the recording mark is formed on the recording medium. On the one hand, over a predetermined period in the space period, the output level of the laser pulse is changed to the low level lower than the normal level. Thereby, the heat accumulation onto the recording medium, due to the transient response of the laser pulse in the mark period, is reduced, and in the mark period after that, the correct recording mark can be formed.
    • 在信息记录装置中,通过与对应于记录信号的脉冲信号驱动光源,将与记录信号对应的激光脉冲照射到记录介质上。 记录信号具有用于形成记录标记的标记周期和不形成记录标记的空间周期。 在标记期间,激光脉冲的输出电平在正常电平和写入电平之间变化,由此在记录介质上形成记录标记。 一方面,在空间周期的预定时间段内,激光脉冲的输出电平变为低于正常电平的低电平。 因此,由于激光脉冲在标记周期中的瞬态响应而在记录介质上的积聚减少,并且在标记周期之后,可以形成正确的记录标记。
