Abstract

Abstract A prerecorded tape-like magnetic record carrier has, on an A and a B side, a number of adjacent tracks (T a .1 to T a .n, T b .1 to T 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 j-1 , FR j , FR 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 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 b .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 (T b .j) on the B side between the end of the information area in the track (T a .i) on the A side and the beginning of the information area in the track on the B side.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 292 words
Prerecorded tape-like magnetic record carrier, comprising music programs recorded on an A and a B side, each of the two sides comprising a number of adjacent tracks running in a longitudinal direction on the record carrier, the tracks on the A side, viewed in a play direction of the A side, containing a lead-in, an information area in which music programs are recorded on the A side, and a lead-out, the tracks on the B side, viewed in a play direction of the B side, containing a lead-in, an information area in which music programs are recorded on the B side, and a lead-out, the information areas on the A and B sides comprising frames of essentially fixed length in which digital audio information, representing the music programs, is included, the lead-ins on the A and B sides comprising frames which contain 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 comprising frames which contain lead-out information, these frames having a length also essentially equal to the length of the frames in the information areas, characterized in that the end of the information area in a track 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 on the B side, in that in the section of the lead-in of said track on the B side, located between the end of the information area in said track on the A side and the beginning of the information area in the track on the B side, there are X lead-in frames, and in that for X it holds that 1≦X≦24.
Claim 2
Dependent Claim 292 words
Prerecorded tape-like magnetic record carrier, comprising music programs recorded on an A and a B side, each of the two sides comprising a number of adjacent tracks running in a longitudinal direction on the record carrier, the tracks on the A side, viewed in a play direction of the A side, containing a lead-in, an information area in which music programs are recorded on the A side, and a lead-out, the tracks on the B side, viewed in a play direction of the B side, containing a lead-in, an information area in which music programs are recorded on the B side, and a lead-out, the information areas on the A and B sides comprising frames of essentially fixed length in which digital audio information, representing the music programs, is included, the lead-ins on the A and B sides comprising frames which contain 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 comprising frames which contain lead-out information, these frames having a length also essentially equal to the length of the frames in the information areas, characterized in that the end of the information area in a track 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 on the B side, in that in the section of the lead-in of said track on the B side, located between the end of the information area in said track on the A side and the beginning of the information area in the track on the B side, there are X lead-in frames, and in that for X it holds that 1≦X≦24.
Claim 3
Dependent Claim 77 words
Prerecorded record carrier as claimed in claim 1, characterized in that the difference (N A -N B ) between the number of frames N A located in the lead in and the information area in said track on the A side, and the number of frames N B located in the information area and the lead out in said track on the B side is equal to Y, and in that for Y it holds that 1≦Y≦24.
Claim 4
Dependent Claim 61 words
Prerecorded record carrier as claimed in claim 1, characterized in that the number of frames located in the lead in, the information area and the lead out in said track on the A side is substantially equal to the number of frames located in the lead in, the information area and the lead out in said track on the B side.
