A recording device (1) comprises receiving means (2) for receiving digital reception data (E) which contain picture, sound and additional information, and processing means (3) for processing received reception data (E) and for supplying digital recording data (AD), a part of the recording data (AD) being formed by information data (ID) which contain additional information, and recording means (4) which include at least two magnetic heads (A, B), mounted on a rotatably supported head disc (14), for the recording of recording data (AD) in helical recording tracks (S) on a magnetic tape (12), information data (ID) being recordable in at least two recording areas which differ as regards their positions in a helical recording track (S), which device now further comprises detection means (31) for detecting additional information contained in reception data (E) and for supplying received detected additional information, and additional information processing means (33) for processing received detected additional information (ZT, ZU) and for supplying information data (ID), the recording means (4) being adapted to record the information data (ID) supplied by the additional information processing means (33) in an information data recording area (SC) which is always the same as regards its position in a helical recording track (S).
