前記記録媒体のコントロールデータゾーンには、上記先頭パルスのパワーレベル、上記中間パルス列の上側パワーレベルと下側パワーレベル、上記最終パルスのパワーレベル、上記負パルスのパワーレベルのそれぞれの指示値が予め記録されており、
上記先頭パルスの平均パワーを上記コントロールデータゾーンの先頭パルスのパワーレベル指示値に調整し、上記中間パルス列の平均パワーを上記コントロールデータゾーンの上側パワーレベル指示値と下側パワーレベル指示値の算術平均値に調整し、上記最終パルスの平均パワーを上記コントロールデータゾーンの最終パルスのパワーレベル指示値に調整し、上記負パルスの平均パワーを上記コントロールデータゾーンの負パルスのパワーレベル指示値に調整し、
前記先頭パルスの前エッジは、現在記録しようとしている当該マークの長さをＭ（ｎ）とし、当該マークに先行するスペースの長さをＳ（ｎ−１）とした場合、Ｍ（ｎ）とＳ（ｎ−１）の組み合わせで決まる値を並べたルックアップテーブルに基づいて決定され、或いは／及び
前記最終パルスの後ろエッジは、現在記録しようとしている当該マーク長さをＭ（ｎ）とし、当該マークに続くスペース長さをＳ（ｎ＋１）とした場合、Ｍ（ｎ）とＳ（ｎ＋１）の組み合わせで決まる値を並べたルックアップテーブルに基づいて決定されることを特徴とする情報の記録方法。In forming one recording mark on the recording medium, and the top pulse, an intermediate pulse train subsequent to said first pulse, a last pulse following the said intermediate pulse train, the pulse train of the energy beam consisting of a negative pulse following the final pulse A method for recording information to be irradiated,
In the control data zone of the recording medium, the indication values of the power level of the leading pulse, the upper and lower power levels of the intermediate pulse train, the power level of the final pulse, and the power level of the negative pulse are stored in advance. It is recorded,
The average power of the first pulse is adjusted to the power level instruction value of the first pulse of the control data zone, and the average power of the intermediate pulse train is the arithmetic average of the upper power level instruction value and the lower power level instruction value of the control data zone. was adjusted to a value, the average power of the last pulse is adjusted to a power level indication value of the last pulse of the control data zone, the average power of the negative pulse is adjusted to a power level indication value of the negative pulse of the control data zone ,
The leading edge of the top pulse is M (n), where M (n) is the length of the mark currently being recorded and S (n-1) is the length of the space preceding the mark. Determined based on a lookup table in which values determined by the combination of S (n-1) are arranged, and / or
The rear edge of the last pulse is M (n) and S (n + 1) when the length of the mark to be recorded is M (n) and the space length following the mark is S (n + 1). A method for recording information, characterized in that the information is determined based on a lookup table in which values determined by combinations are arranged .
