Abstract
A prerecorded tape-like magnetic record carrier has, on an A and a B side, a number of adjacent tracks (T.sub.a.1 to T.sub.a.n, T.sub.b.1 to T.sub.b.n) running in a longitudinal direction on the record carrier, the tracks on the A side, viewed in the play direction of the A side, having a lead-in (LI), an information area (IA) in which music programs are recorded on the A side, and a lead-out (LO), the tracks on the B side, viewed in the play direction of the B side, having a lead-in (LI), an information area (IB) in which music programs are recorded on the B side, and a lead-out (LO). The information areas on the A and B sides include frames ( . . . , FR.sub.j-1, FR.sub.j, FR.sub.j+i, . . . ) of an essentially fixed length in which digital audio information representing the music programs are recorded. The lead-ins on the A and B sides include frames with lead-in information, these frames having a length essentially equal to the length of the frames in the information areas. The lead-outs on the A and B sides include frames with lead-out information, these frames having a length likewise essentially equal to the length of the frames in the information areas. The end of the information area in a track (T.sub.a.i) on the A side, viewed in the play direction of the A side, is located past the beginning of the information area in a track (T.sub.b.j) on the B side, in such a way that X lead-in frames, where for X it holds that 1.ltoreq.X.ltoreq.24, are located in the section of the lead-in of said track (T.sub.b.j) on the B side between the end of the information area in the track (T.sub.a.i) on the A side and the beginning of the information area in the track on the B side.
