摘要：
An optical recording medium includes grooves and lands on a substrate in which prepits are disposed on an extension of the boundary between a groove and a land such that they are located uniformly on both sides of the center line of the groove or the land and that they do not exist on the both sides of any specific position of the center line of the groove or the land. Through this, address data would be obtained with ease and tracking offset would be decreased.
