ている。First, a conventional audio signal recording method will be explained with reference to Figure @1. In Figure 1, TP indicates a magnetic tape, which has inclined magnetic tracks Tl, T2...
A video signal (1) and four channels of audio signals Al to A4 are recorded so as to be formed as follows. In this case, the video signal V is a digital video signal, and the 4ka track T

、これは鼻先オーディオ信号の品質低下につながる。In the conventional audio signal recording system, multi-channel audio signals are recorded at high density in the longitudinal direction of a magnetic track with time pressure ends, and the chronological position of the audio signal of each channel is Since the inclined magnetic tracks Ktjk are arranged in 11th order, if a scratch occurs in the longitudinal direction of the magnetic tape, the audio signal of the same channel will be transmitted over many magnetic tracks during playback. , there is a risk of dropouts, which leads to a reduction in the quality of the nasal audio signal.

。In view of the above points, one object of the present invention is to propose an audio signal recording system in which audio signals of the same channel are less likely to be lost even if there are scratches in the longitudinal direction of the magnetic tape.

る。The 4-channel audio signals At to A4 are transferred to the +S oblique magnetic track T1. T2... This is a case where the rotation is made to change cyclically every φ. However, this method of change is also possible for ranterms. Further, the number of channels can be any number such as 4 channels or 2 channels.

号は、回路的に補填することができる。In addition, since the audio signal of the Xth channel does not drop out across a large number of magnetic tracks during playback, the partially missing audio signal of the specific channel can be compensated for using a circuit.

ことができる。In addition, in this actual MFL, it is assumed that a digital video signal and a digital audio signal are distributed on one inclined magnetic track. However, an analog video signal and an analog audio signal may be used, respectively. Only digital or audio signals may be recorded on the track. In that case, for example, four channels of audio signals can be repeatedly recorded on one inclined magnetic track.

とができる。According to the present invention #4 described above, multi-channel audio signals are transferred to an inclined magnetic track on a magnetic tape in the direction of the prosthetic hand K.
In an audio signal recording system in which each channel is recorded separately using fgj, it is possible to obtain a system in which there is no possibility that the audio signal of the same channel will drop out during playback even if a scratch occurs in the direction of the magnetic tape. can.
