Abstract
Abstract An apparatus for recording a plurality of audio signals on a slant track of a helically scanned tape. The tape is divided into a plurality of segments (51-55,61-65). A digitized audio signal may be recorded at each of the segments (51-55, 61-65). A control signal (58) is supplied and recorded at a beginning of each segment (51-55, 61-65). The control signal (58) can be used for controlling an operation of the apparatus when the control signal (58) is reproduced.

Claim 1
Independent Claim
117 words
An apparatus for recording an information signal comprised of at least an audio signal on a recording medium having a slant track format, characterized in that a) audio signal processing means (6,8) for converting said audio signal into digital form; b) transducer means (4,5, 11-18) connected to said processing means (6,8) for recording at least said digitized audio signal at a part (51-55) of a slant track on said recording medium; and c) control signal means (9,10, 19-28) for supplying a control signal to said transducer means (4,5, 11-18) to be recorded at a position near said part, said control signal being useful for controlling an operation of a reproducing apparatus which reproduces the digitized audio signal.
Claim 2
Independent Claim

An apparatus for recording an information signal comprised of at least an audio signal on a recording medium having a slant track format, characterized in that a) audio signal processing means (6,8) for converting said audio signal into digital form; b) transducer means (4,5, 11-18) connected to said processing means (6,8) for recording at least said digitized audio signal at a part (51-55) of a slant track on said recording medium; and c) control signal means (9,10, 19-28) for supplying a control signal to said transducer means (4,5, 11-18) to be recorded at a position near said part, said control signal being useful for controlling an operation of a reproducing apparatus which reproduces the digitized audio signal.
Claim 3
Dependent Claim
46 words
An apparatus according to claim 1, characterized in that said transducer means (4,5, 11-18) also reproduces said control signal and said digitized audio signal; and characterized in control means for controlling an operation of said apparatus when said control signal is reproduced by said transducer means.
Claim 4
Dependent Claim
26 words
An apparatus according to claim 1 or 2 characterized in that the transducer mean_st4,5, 11-18) records a video signal on another part of said slant track.
Claim 5
Independent Claim
34 words
An apparatus according to anyone of claims 1 to 3 characterized in that a second digitized audio signal is also recorded by said transducer means (4,5, 11-18) at another part of said slant track.
Claim 6
Independent Claim
80 words
An apparatus according to any one of claims 1 to 4, characterized in that a remaining part of the track not allocated for the first mentioned digitized audio signal is divided into a plurality of additional parts (61-65), each of which is equal in length to said first mentioned part (51-55) of the slant track, and wherein at least a second digitized audio signal is recorded by said transducer means (4,5,11-18) into at least one of said additional parts (61-65).
Claim 7
Independent Claim
72 words
An apparatus for recording and/ or reproducing a plurality of information signals on a helically scanned recording medium, characterized in a recording medium; helical scanning means (13,14,19) for scanning slant tracks on the recording medium; means for selectively recording at least two parts (51-55, 61-65) of a slant track at least two respective information signals; and means for recording a respective control signal at each of the parts on the slant track.
Claim 8
Independent Claim
