Abstract

PURPOSE:To obtain a high-quality picture, by recording the luminance and chrominance signals with different heads. CONSTITUTION:The luminance signal applied to an input terminal 1 is recorded on a tape by a head 12. The signal I applied to an input terminal 2 and the signal Q applied to an input terminal 3 are synthesized at an adder 9 and then recorded on a tape through a head 13. In a reproduction mode, the luminance signal reproduced by the head 12 is delivered through an output terminal 21. While the chrominance signal reproduced by the head 13 is delivered through output terminals 22 and 23 in the form of reproduced signals I and Q respectively.
