Abstract: An optical record carrier (1) is provided with tracks having a groove (4) wobbled in a radial direction and predetermined positions (18) along the track. Embossed pits (19) at the predetermined positions represent addressing information. The phase of the wobble near the predetermined positions depends on whether a pit is present (19) on a predetermined position or not (20).
