Abstract

PURPOSE:To facilitate an easy control of the recording current according to the level of the reproduced signal, by inserting and recording the discrimination signal of each recording head with every track during a dubbing and then discriminating the head of the recording mode with the discrimination signal during a reproduction. CONSTITUTION:In the case of a 5-fold speed dubbing, the signals reproduced from the tape 7 and through the heads 51-55 are recorded on the tape 8 by the reproducing amplifiers 91-95 plus the recording amplifiers 101-105 and via the heads 61- 65. In this case, the vertical synchronous signal VD is sampled out of the reproduced signal of the head 51 through the vertical synchronous separating circuit 11, and thus a blank part is recorded on the tape 8 at the period corresponding to the signal VD. The tape 8 thus dubbed is reproduced through the head VTR, and thus the position of the blank part has a shift with every field. Then a correspondence is given between the both blank parts to secure a discrimination among the heads 61- 65 during a recording. In such way, an easy control is possible for the record current.
