Abstract
A record carrier () has a servo track () indicating an information track () intended for recording information blocks represented by marks. The servo track () has a periodic variation of a physical parameter at a predetermined frequency and modulated parts for encoding position information at regular intervals. The modulated parts start with a bit sync element and are of a data type having a data bit element or of a word sync type having a word sync element. The bit sync element and the data bit element are modulated according to a same predetermined type of modulation of the periodic variation. The modulated parts further include modulated parts () of an isolated bit sync type only having the bit sync element.
