<p>The optical storage medium comprises a substrate layer and a data layer disposed on the substrate layer, the data layer having a mark/space data structure being arranged in tracks (T m , T n ), wherein on a first track (T m ), the marks (31) are enlarged in length and the spaces (32) are shortened in length, and on an adjacent track (T n ), the marks (33) are shortened in length and the spaces (34) are enlarged in length. The track pitch (TP) between adjacent tracks (T m , T n ) is particularly below a diffraction limit of »/2*NA of a pickup for reading of the data.</p> |
