    摘要: In an optical recording medium comprising a substrate including parallel extending lands and grooves on one surface thereof, the grooves serving as recording tracks, and the lands being formed with prepits, the height HP of the land disposed between the prepit and the groove divided by the height HL of the land in a prepit-free region, both as measured from the groove bottom, i.e., HP/HL ranges from 0.25 to less than 1. This enables to significantly increase the recording density of the medium without a substantial cost increase.
