ABSTRACT:
A switch is provided which successively switches contacts at a timing sufficiently quick with respect to reproduced signals in reproducing a magnetic tape on which digital recording is effected, and which switches contacts at similar timing in reproducing a magnetic tape on which analog recording is effected. On signals provided through this switch and through an analog-digital converting circuit, processing such as waveform equalization corresponding to the type of magnetic tape is effected by a digital equalizer. By this digital equalizer, correction of frequency characteristic in accordance with the type of the magnetic tape and correction of frequency characteristic inherent to the head per se are effected.
