Abstract

PURPOSE:To obtain an excellent reproduced picture by placing the position of a noise band, when a control signal recorded in long-period mode is reproduced in normal mode, in a vertical blanking interval in skip recording. CONSTITUTION:With switch 10 placed at the contact 9 side in normal mode recording, vertical synchronizing signal (a) from input terminal 2 is shaped by monostable multivibrator 5 into the 1st reference pulse (b), which is recorded on a tape as a control signal. With the switch changed over to the contact 8 side in long-period mode recording, vertical synchronizing signal (a) that corresponds to a video signal of a field to be skip-recorded and frequency-divided pulse (c) from input terminal 1 are applied to gate circuit 3 and monostable multivibrator 4 outputs the 2nd reference pulse (e), which is recorded. Thus, even when the skip recording part is reproduced in normal mode, the leading edge of the pulses of signal (e) is placed in the vertical blanking interval by setting monostable multivibrator 4 previously, so that an excellent reproduced picture can be obtained.
