A magnetic reproducing device that reproduces data using a plurality of double azimuth heads, further comprising a preamplifier that amplifies a reproduced signal from one of the double azimuth heads, and a level of an output signal of the preamplifier is lower than a predetermined level. a detector that detects that the magnetic tape has decreased and outputs a detection signal; and a signal generator that generates a pulse signal with a predetermined pulse width depending on the running speed of the magnetic tape based on the detection signal input from the detector. and, provided between the double azimuth head and the preamplifier, the supply of the pulse signal from the signal generator selects up to that of the double azimuth head during the pulse width of the pulse signal. 1. A magnetic reproducing apparatus comprising: switching means for switching selection from one magnetic head to the other magnetic head, and supplying a reproduction signal from the other magnetic head to the preamplifier.
