A record carrier (1) has a servo track (4) indicating an information track (9) intended for recording information blocks represented by marks, this servo track (4) having a periodic variation of a physical parameter. Due to cross-talk, there exists a variation in the wobble signal called wobble beat. The track pitch t and the wobble period p, p being the length of a wobble period, are chosen in such a way that 2πt/p≈n+½ where n is integer. The choice results in a reduced wobble beat. A recording and/or playback device has apparatus for recording/reading the information blocks and for generating a wobble signal.
