Claims

[Scope of utility model registration request]

In a tape duplication device that reproduces signals recorded on a master tape having multiple tracks and simultaneously records them on multiple tracks of a slave tape,
a plurality of master playback heads for playing back a plurality of tracks on the master tape; a plurality of master playback amplifiers for respectively amplifying the signals played from the plurality of master playback heads; and a plurality of master playback amplifiers for respectively amplifying the output signals of the plurality of master playback amplifiers. A plurality of recording amplifiers and a plurality of recording heads record on the slave tape, a plurality of slave playback heads play back the recorded signals of the slave tape for each track, and the signals of the plurality of slave playback heads are added together. a first rectifying means for adding and rectifying the output signals of the plurality of master reproducing amplifiers, and an output of the first rectifying means and an output of the second rectifying means. Compare the
1. A tape duplication device comprising a comparison detection means for inverting the output state when one output is too large or too small compared to the other output.
