Zusammenfassung: | PURPOSE:To prevent the deterioration of quality of the sound signal to be recorded, by giving a high speed enough to record the video signal to the relative speed between a magnetic head and a magnetic tape. CONSTITUTION:The left sound signals LF1 and LF2 and right sound signals RF3 and RF4 which are FM modulated 6, 7, 11 and 12 through RPF13 and 14- 16 are distributed to the frequency band between the frequency band of the carrier chrominance signal C and the frequency of the FM modulated luminance signal Lm, which is higher than the signal C. The level of each of these sound signals is set lower than those of the signals C and Lm. At the same time, the levels of those at the low band side are set lower than those at the high band side among the signals LF1, LF2, RF3 and RF4. Then the signals C, Lm, LF1, LF2, RF3 and RF4 are recorded on a magnetic tape by recording heads 28 and 30 after forming a common recording track. |
