Abstract
A magnetic tape reproducing apparatus includes a plurality of playback heads, a plurality of damping circuits for damping output signals from the associated playback heads, a switching circuit for sequentially passing the output signals from the plurality of damping circuits, a reproduction equalizer for creating substantially a total reproduction equalizing characteristic for the output signal from the switching circuit which signal is subjected to a peaking characteristic, and a signal processor for converting the output signal of the reproduction equalizer to a recorded information signal. Each damping circuit serves to damp the output from the associated playback head so that the peaking characteristic created by its equivalent resonant capacitance, its equivalent damping resistance, the inductance of the associated playback head and the capacitance thereof does not govern the total equalizing characteristic.
