    摘要: An information recording medium capable of displaying multiple labels and a storing case for the information recording medium are provided. The multiple labels are displayed by changing the labels to be displayed while selectively selecting information layers in a multi information recording medium. The medium has a function to receive either voltage or current, and the information layers selectively receive either voltage or current for changing the labels.

    摘要: 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.
