Abstract
PURPOSE: To prevent sound quality from lowering and also to dectct a control signal definitely, by providing a method of detecting only a control signal frequency component in reproduction and that which does not detect the same component and by omitting HPF.
CONSTITUTION: The record a control signal, switch S4 is connected to side (a) and the control signal from control signal oscillation circuit 4 is recorded through terminal R.HEAD. In this case, the recording of a sound signal is interruped. In reproduction, a signal detected by terminal P.HEAD is amplified by pre-amplifier 1 and branched. The 1st signal is amplified by main amplifier 3 to obtain a sound signal from terminal S.P. The 2nd one is inputted to integrating circuit 6 through BPF5. The 3rd one is inputted to integrating circuit 8 after its control signal frequency component is removed by tape circuit 7. Output C of circuit 8 is inverted by inverter 9 to obtain signal D, which is applied to AND gate 10 together with output B of circuit 6, thereby obtaining output E.
