Abstract

An optical record carrier (10) comprises a recording layer for recording information in a pattern of optically detectable marks in substantially parallel tracks. The tracks comprise alternating first and second servo tracks (11, 13). The servo tracks have a track modulation different from the information pattern and indicative of position information. The track modulations of the first and second servo tracks comprise different position information and have a fixed phase relation.
