    • An information recording apparatus for injecting an energy beam into a recording medium to form locally a region different in physical properties from a non-recording region to thereby record information, has a drive for driving an energy generation source for changing the number of injected energy pulses in a mark forming period in accordance with the mark length so that the interval between arbitrary two points of the change of injected power level at the time of information recording is substantially set to be longer than a half of a detection window width in order to make it easy to drive a recording energy generation source to thereby form said mark accurately and speedily and, at the same time, in order to secure a sufficient time required for cooling the recording medium.
    • 一种信息记录装置,用于将能量束注入到记录介质中以在局部形成与非记录区域不同的物理区域,从而记录信息,具有驱动用于改变喷射能量脉冲数的能量产生源的驱动装置 在标记形成期间,根据标记长度,使信息记录时的注入功率电平变化的任意两点之间的间隔大致设定为长于检测窗宽度的一半,以便使 可以容易地驱动记录能量产生源,从而准确且快速地形成所述标记,同时,为了确保冷却记录介质所需的足够的时间。
