| Summary: | 1. Field of the Invention
An optical disc comprises; a substrate; grooves concentrically or helically formed on the substrate in each of which data is recorded; lands defined between the adjacent grooves; and prepits formed on the lands, wherein each of the prepits is disposed to be shifted from a center line of the land toward a groove to be paired without overlapping with adjacent tracks, whereby reducing cross-talk from adjacent tracks and improving the density of recorded data. |
