摘要：
An information recording medium having spiral or concentric-shaped groove structure along a track formed on a disk-like substrate. The medium has the groove structure wobbled in a radius direction of the medium and the track is divided into a plurality of recording units in the track direction by at least one radial boundary. At least two adjacent recording units in the track direction of the medium comprise one zone and the medium includes a plurality of the zones. The groove structure included in the adjacent recording units within any zone has substantially the same number of wobbling.
