ABSTRACT:
A recording and reproducing apparatus is to monitor the information to be recorded actually by the recording heads. The recording and reproducing apparatus comprises a digital mixer for inputting signals from the multiple preceding reproducing heads corresponding to the multiple recording tracks respectively and performing the prescribed signal processes and simultaneously outputting the signals inputted to the monitor speaker, and cross fader circuits for shifting signals from the digital mixer or the multiple preceding reproducing heads and outputting to the recording heads placed on the back of the preceding reproducing heads, and which is adapted to rewrite the information recorded on the first recording track of the recording medium to the second recording track. The signals outputted from the preceding reproducing heads or the signals outputted from the cross fader circuits to the recording heads is shifted every multiple recording tracks and inputted to the digital mixer and thus by means of monitoring the signals outputted to the recording heads by the speaker for monitor, the record information to be actually rewrote can be monitored.
