Abstract
PURPOSE:To set the optimum value of the recording property when a magnetic tape travles backward, by recording the reference signal after varying one of a record equalizer, bias and level while transporting the magnetic tape in a single direction. CONSTITUTION:During the control of a record equalizer, switches S2a, S2b and S2c are switched to the EQ side to secure the recording mode. Thus a counter 4 of oscillation 1 starts counting and at the same time control signal frequencies f1 and f2 are recorded on a tape 11 for a multivibrator 3. A record equalizer setting circuit 7 controls the level successively and according to the count contents of the counter 4. The recording mode is cancelled by the carry output of the counter 4. At the same time, the tape is controlled backward to secure the reproduction mode. The DC level is obtained for the reproduced signal through a separating circuit 14 and in accordance with the level of f1 and f2 respectively. Then a flip-flop 30 is inverted when a coincidence of the level is obtained through a comparator 17. Thus a switch S1 opens to set EQ. Thereafter, the bias and level are controlled.
