Abstract

PURPOSE:To reduce the capacity of a coupling capacitor in a reproducing amplifier and to form the reproducing amplifier as an IC by reproducing a digital signal recorded on a tape based on a differential signal obtained by differentiating an ordinary reproducing signal. CONSTITUTION:Since the coupling capacitor C inserted between 1st and 2nd reproducing amplifiers 3, 4 in a reproducing circuit is reduced at its capacity so that both the amplifiers 3, 4 can be easily formed as ICs, an output signal goes to a differential signal obtained by differentiating the waveform of an originally reproducing signal. The output of the reproducing circuit is connected to a digital signal detecting circuit. Thereby, a digital signal detecting circuit can reproduce a digital signal similar to an originally one based on a differential signal D read out from the reproducing circuit. Consequently, the reproducing amplifiers 3, 4 can be easily formed as ICs.
