ABSTRACT:
A magnetic reproduction device includes a comparator for comparing the level of reproduced signals obtained by tracing the same track with magnetic heads having different azimuths, and switches for selecting and supplying any of the reproduced signals in accordance with the result of the comparison. The magnetic heads thus used for reproduction are therefore determined simultaneously with the start of reproduction. This allows for the automatic supply of correct reproduced signals, even if an azimuth of the magnetic heads which recorded the signals is unknown.
