A method and apparatus for recording data on an optical recording medium are provided. In the method of recording data on the optical recording medium, a mark or a space is formed using a recording waveform having an erase pattern including a predetermined pulse whose high level is higher than an erase power level and whose low level is lower than the erase power level. Thus, the shape of the mark can be prevented from being distorted and be improved, which results in an improvement in the recording/reproducing characteristics.

Il s'agit d'une méthode et d'un appareil d'enregistrement de données sur un support d'enregistrement optique. Dans cette méthode, une marque ou un espace sont formés en faisant appel à une forme d'onde d'enregistrement qui présente un diagramme d'effacement comprenant une impulsion prédéterminée dont le niveau élevé est supérieur à un niveau d'intensité d'effacement, et dont le niveau faible est inférieur au niveau de l'intensité d'effacement. Par conséquent, la forme de la marque ne peut pas être déformée, mais être améliorée, ce qui résulte en un amélioration des caractéristiques d'enregistrement et de reproduction.
