The present invention relates to an information carrier for storing user-data, said information carrier comprising a wobbled pre-groove having stored a wobble information and comprising sinusoidal wobbles. The wobble information is encoded by use of ADIP units, which are formed by sequences of sinusoidal wobbles having embedded patterns of MSK marks. In order to avoid the use of an MSK mark present at the beginning of each ADIP unit, as according to Blue-ray Disc, and the consequent wobble beat, a new set of ADIP units is introduced wherein MSK marks are disposed in patterns according to which no mark is in a common position in all the set of ADIP units. The invention further relates to a device and a method for reading the wobble information from the information carrier, and to a recording apparatus and method for recording user-data therein. |
