Abstract

PURPOSE: To reproduce control pulses with good S/N by differentiating the square wave signal being recorded as control pulses thereby attenuating the signal components which become crosstalk.
CONSTITUTION: In the case where the signal Sv from a frequency dividing circuit 52 is made to differential pulses Pd in a differentiating circuit 61, the time constant of the circuit 16 is set at the value at which the basic wave components and the higher harmonic components of the 3rd, 5th and 7th orders of the signal Sv sufficiently attenutate, whereby the pulses in which the levels of the components becoming crosstalk is small are obtained. Next, the pulses Pd are supplied to a magnetic head 57 through a bias trap 62 and the recording side contacts R of a recording- reproducing changeover switch 43 and at the same time the oscillation signal of the specified frequency from an oscillation circuit 53 is supplied as an AC bias signal to the head 57 through the contacts R of the switch 43, whereby the pulses Pd are AC-bias-recorded in the tracks of a tape 1. Thereby, the contorol pulses may be reproduced with good S/N.
