Abstract
A recording device (1) includes a receiver (2) for receiving digital reception data (E) which contain picture, sound and additional information, a processor (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 a recording unit (4) which includes 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). The recording device now further includes a detection unit (31) for detecting additional information contained in reception data (E) and for supplying received detected additional information, and an additional information processor (33) for processing received detected additional information (ZT, ZU) and for supplying information data (ID), the recording unit (4) being adapted to record the information data (ID) supplied by the additional information processor (33) in an information data recording area (SC) which is always the same as regards its position in a helical recording track (S).
