摘要： An optical recording medium is designed to generate a read signal free from waveform distortion during reproduction of information. The optical recording medium is formed with information tracks on which data pits carrying information data is to be formed, and prepit tracks previously formed with a plurality of prepits. Each of the information tracks and each of the prepit tracks are positioned adjacent to each other, and each of the prepits is formed to be spaced apart from adjacent information tracks in at least its bottom part.

摘要： When a bias power level of a recording pulse waveform is varied entirely or partially, a shape of the recording pulse wave form is varied according to the variation. For example, when the bias power level is increased, a width or an edge position of a top pulse or a multi-pulse of the recording pulse waveform is varied correspondingly. Thereby, a total heat quantity of a recording laser light is not increased, and a preferable recording characteristic is maintained.

摘要翻译： 当记录脉冲波形的偏置功率电平完全或部分地变化时，记录脉冲波形的形状根据变化而变化。 例如，当偏置功率电平增加时，记录脉冲波形的顶部脉冲或多脉冲的宽度或边缘位置相应地变化。 因此，记录激光的总热量不增加，并且保持优选的记录特性。

The optical recording medium comprises groove information tracks on which information pits carrying information data is to be formed, and prepit tracks provided with a plurality of previously formed land prepits connected to the groove information tracks. The groove information tracks and the prepit tracks are arranged in alternation. The groove information track has a track width smaller in at least a part of each of sections in which the land prepit exists than in sections in which no land prepit exists.
