Abstract

PURPOSE: To eliminate the evil effect given to the record signal through a simple circuit by inserting the DC blocking capacitor between the output terminals of the record amplifier and the bias amplifier.
CONSTITUTION: The serial resonance is caused by capacitor 14 and record head 7. For the frequency property, the response reaches its peak at serial resonance frequency f1 and is made flat with connection of resistor 15 featuring a comparatively large value to be then increased at serial resonance frequency f2 and with connection of capacitor 16. Frequency f2 is almost decided by the inductance of head 7 and the capacitance of capacitor 16. And if this frequency is selected at about 30KHz, the high band correction becomes possible without providing the peaking circuit to the record amplifier. Also the vias level can be varied according to the types of the magnetic tapes by connecting the variable resistor in the necessary number of units in parallel to variable resistor 17. Thus the evil effect given to the record signal can be eliminated in a simple way.
