A method and device for recording information signals on a partly recorded writable record carrier (), e.g., an optical disc. An information signal represents at least one information unit. The record carrier has a recording track which includes preformed track position information indicative of locations for recording the information units. From the information signal, a modulated signal is generated having successive frames, each frame including a synchronizing signal. The modulated signal is recorded at a one of the locations, while maintaining a fixed relationship between the track position information and the synchronizing signals. In the event that the location is after and adjacent to an already recorded location, the recording is started at a link position () before the end of a last frame of the earlier recorded information signal, at a predefined distance before a first synchronizing signal () of the modulated signal.

Method and device for recording information in units

A method and device for recording information signals on a partly recorded writable record carrier (), e.g., an optical disc. An information signal represents at least one information unit. The record carrier has a recording track which includes pre-formed track position information indicative of locations for recording the information units. From the information signal, a modulated signal is generated having successive frames, each frame including a synchronizing signal. The modulated signal is recorded at a one of the locations, while maintaining a fixed relationship between the track position information and the synchronizing signals. In the event that the location is after and adjacent to an already recorded location, the recording is started at a link position () before the end of a last frame of the earlier recorded information signal, at a predefined distance before a first synchronizing signal () of the modulated signal.
