ABSTRACT:
Provided is a magnetic tape reproduction device which comprises a tape driving circuit for driving a magnetic tape, first and second reproducing heads disposed respectively in correspondence to first and second tracks of the magnetic tape, and an auto-reverse circuit for automatically reversing the magnetic tape by detecting a terminal end thereof. The auto-reverse circuit sets the second reproducing head to a mode of reproduction when the first reproducing head reproducing the recorded information of the magnetic tape has detected that an output signal corresponding to a non-signal portion of the magnetic tape continues to be generated for a specified period of time, and, when the second reproducing head set to the mode of reproduction has detected that an output signal corresponding to a non-signal portion of the magnetic tape continues to be generated for a specified period of time, supplies a reverse signal to the tape driving circuit.
