A high speed dubbing apparatus for producing magnetic tapes such as video, audio or computer soft tapes, is provided. Typical form of the apparatus may comprise 3 master tape playback devices for synchronously playing back 3 divided master tapes respectively recorded with 3 divided master signals obtained by dividing time-divisionally an original master signal having an original data sequence by 3 and for outputting the 3 divided master signals, a triple speed recording signal producing device for time-compressing each of the 3 divided master signals to 1/3 to obtain a triple speed recording signal from the 3 divided master signals while restoring the original data sequence in the triple speed recording signal and a recording device for recording the triple speed recording signal on a plurality of slave tapes running at a speed which is 3 times the normal playback speed of the slave tapes.
