Title: Video tape recorder
Inventor: NAGANO YASUYUKI
IPC: G11B5/027
Filed: 1989-05-17
Abstract: PURPOSE:To prevent the quality deterioration of a sound signal by selecting a side to be distant from a sound FM carrier frequency when two kinds of video carrier frequencies exist, and supplying it to a rotary head simultaneously with a sound FM signal at the time of recording only the sound signal. CONSTITUTION:The recorder has an FM modulating circuit (S-VHS specification) 1 for high picture quality in which the carrier frequency at the time of non-modulation is 5.4MHz, and a standard FM modulating circuit 2 in which the carrier frequency at the time of non-modulation is 3.4MHz. When an S-VHS tape is loaded to the VTR, when the instruction of the S-VHS is executed and when the recording mode of only the FM sound signal is instructed, the modulating circuit 1 is selected by the action of a logic circuit 3. In such a case, when the recording of only the FM sound signal is executed, the non- modulation carrier signal 1 of the higher side is always supplied to a head 6 for video. Thus, the voice quality can be improved while maintaining a compatibility.
