Title: Recording method for information signal
Inventor: NISHIKAWA MASATOME
IPC: H04N5/922
Filed: 1978-12-18
Abstract: PURPOSE: To ensure reproduction of the high-quality information signal by eliminating or attenuating the upper side band component in case the information signal is converted into the frequency modulation signal for recording.  
     CONSTITUTION: For instance, luminance signal Sy is supplied to frequency modulator circuit 14 through input terminal 11 and others and thus chanbed into frequency modulation signal Sf to be supplied to LPF15. Through LPF15, signal Sf is turned to LSB signal SI with the upper side band component removed from signal Sf and then supplied to two rotary magnetic heads 2A and 2B through record amplifier 16 to be recorded sequentially on magnetic tape 1. Thus both the original frequency modulation component and the frequency modulation component converted from the amplitude modulation component are recorded in the same phase when signal SI is recorded on tape 1. As a result, the reproduction level can be increased, thus ensuring high-quality luminance signal Sy with a high S/N ratio.
