Patent EP-0101179-A3 (EP)
IPC: H04N9/79
Filed: 1983-07-07
Abstract: This invention reduces crosstalk interference compo­
nents without a significant increase in recorded bandwidth of 
the modulated audio signals and without a significant 
degradation of the signal-to-noise ratio of the reproduced 
audio signals. According to the invention, the nominal carrier 
frequency of the modulated audio signal in adjacent tracks or 
scans is offset by an amount sufficient to shift the crosstalk 
interference components outside the desired audio pass 
band for substantially all modulating amplitudes and fre­
quencies. At the same time, the modulated audio frequency 
spectra of the adjacent tracks substantially overlap so that 
additional overall bandwidth requirements are minimized. A 
satisfactory offset from track to track is in the order of twice 
the maximum audio response frequency. As the offset is 
reduced or as occasional high frequency high amplitude 
audio occurs in adjacent tracks, crosstalk distortion compo­
nents will tend to appear beginning at the high frequencies. 
Such crosstalk interference can be further reduced by the use 
of frequency dependent compressor-expander noise reduc­
tion because of the audio band rather than across the entire 
audio band as in the case of no track-to-track carrier offset. In 
one example audio signals are frequency modulated and 
recorded on a helical scan recorder using carrier frequencies 
f₁ and f₂ for odd and even scans. On playback the signals 
from odd and even scans are processed by respective 
limiters 6 and 8 respective demodulators 10 and 12 and 
respective high pass filters 14 and 16.
