Abstract

PURPOSE: To increase the linearity of the output voltage by inputting the bias current and recording signal current to the second inversion and non-inversion amplifiers via the first inverting amplifier and connecting recording head between the outputs of the said both amplifiers.
CONSTITUTION: The recording signal of the recording signal source 1 and the bias signal of the bias signal generator 7 are respectively inputted to the inverting amplifier 11 via the resistors 9 and 10, and the recording head 10 is connected between the outputs of the said amplifiers 12 and 13. Taking the recording signal voltage as e1, the voltage at the output point e of the inverting amplifier 11 as ea, the resistance values of the resistor 9 and the negative feedback resistor 14 as R9, R14, and the voltage fed to the recording head 8 as er, the relation of equation I is established. That is, the recording signal ei is multiplied by R14/R9 and the voltage ea is swung to the power supply voltage approximately. Accordingly, the application of the voltage up to twice the power supply voltage of the maximum is possible for the terminals of the recording head and the linearity of the output voltage can remarkably be increased.
