PHQ 91-025 08.05.1992 Prerecorded record carrier. A prerecorded tape-like magnetic record carrier has on an A and a B side a number of adjacent tracks (Ta,1 to Ta.n,Tb.1 to Tb.n) running in longitudinal direction on the record carrier, the tracks on the A side, viewed in the play direction of the A side, comprising a lead in (LI), an information area (IA) in which the 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, comprising a lead in (LI), an information area (IB) in which the music programs are recorded on the B side, and a lead out (LO). The information areas on the A and B sides comprise frames (...,FRJ-1, FRj, FRj, FRj+l, ...) 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 comprise 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 comprise 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 (Ta,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 (Tb.j) on the B side, in such a way that X lead in frames, where for X it holds that 1? X ? 24, are located in the section of the lead in of said track (Tb.j) on the B side between the end of the information area in said track (Ta.j) on the A side and the beginning of the information area in the track on the B side.
