Abstract

PURPOSE:To prevent malfunction due to a false iD signal by deciding an iD signal to be true of false and erasing forcibly the false iD signal when the false iD signal is decided. CONSTITUTION:An output of an amplifier circuit 4 is peak detected by a peak detecting circuit 7, and its peak detected output is compared with a prescribed level by a comparator circuit 8. Now, when the output of the comparator circuit 8 is larger than the prescribed level, an separated iD signal is decided to be 'true', so that the iD data signal is reproduced. Then, when the output of the peak detecting circuit 7 is lower than the prescribed level, the decision is made as the false one without recording the true iD signal, so that its false iD signal is forcibly erased by changing changeover switch 9 to the GND side. By this method, the malfunction, such as frame reproducing of a field recording by mistake is eliminated.
