摘要：
An optical recording medium which can produce a read signal free from waveform distortion during reproduction of information. 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.
