    • A method for recording information is disclosed in which an information recording medium is irradiated with a recording energy beam power-modulated into at least a record power level and a record-ready power level lower than the record power level. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion. Also, only in the case where the energy beam is modulated by the power lower in power level than the record-ready power level after the last pulse of the energy beam pulse train including at least one pulse for forming a mark portion and the mark portion is followed by a space portion of a predetermined length, the particular radiation energy of low power level is reduced as compared with when the mark portion is followed by a space potion of a different length. The radiation energy is increased and/or decreased.
    • 公开了一种用于记录信息的方法,其中信息记录介质被照射到被调制成至少记录功率电平和低于记录功率电平的记录就绪功率电平的记录能量束。 当形成预定长度的标记部分时,与在至少包括用于形成的脉冲的能量束脉冲序列的第一脉冲之前或之后形成不同长度的标记部分相比,能量束的辐射能量增加 标记部分。 此外,只有在包括至少一个用于形成标记部分的脉冲的能量束脉冲序列的最后脉冲之后,能量束被功率电平低于记录就绪功率电平的功率调制的情况下,以及标记部分 之后是预定长度的空间部分,与标记部分之后是不同长度的空间部分相比,低功率电平的特定辐射能量减小。 辐射能量增加和/或减少。
