    • A multi-layered high-density recording medium and an optical power adjusting method for use with the same. Control information is pre-recorded in a specific area of at least a specific recording layer among the multiple recording layers, wherein the control information and includes each reference power information for respective recording layers. The method includes: (a) reading control information from a specific area of the recording medium, wherein the control information includes each reference power information for respective recording layers and is pre-recorded in the specific area of at least a specific recording layer among the multi recording layers; (b) adjusting a power value to be used for at least one of a recording operation and a reproducing operation at a target recording layer, by referring to the read control information; and (c) performing at least one of the recording and reproducing operations based on the adjusted power value.
    • 一种多层高密度记录介质和与其一起使用的光功率调节方法。 控制信息被预先记录在多个记录层中的至少特定记录层的特定区域中,其中控制信息包括各个记录层的每个参考功率信息。 该方法包括:(a)从记录介质的特定区域读取控制信息,其中控制信息包括各个记录层的每个参考功率信息,并被预先记录在至少一个特定记录层的特定区域中 多层录音; (b)通过参考读取的控制信息来调整要用于目标记录层的记录操作和再现操作中的至少一个的功率值; 和(c)基于经调整的功率值执行记录和再现操作中的至少一个。
