Abstract

PURPOSE:To obtain a recorder which contributes the improvement of the efficiency of editing operation, etc., with simple constitution and easy operation, by providing specific gate circuits and gate control circuits. CONSTITUTION:A gate 28 is interposed between an encoding circuit 14 and a recording medium 21. A gate control circuit couples with a level limiter 13 to record specific digital data on a recording medium 21 by closing the gate circuit 28 while an analog information signal is held at a prescribed level by the level limiter 13, and also to record a digital encoded signal outputted from the encoding circuit 14 on the recording medium 21 by opening the gate circuit 28 while the analog information signal is held at a level different from said one by the level limiter 13. For example, a circuit shown in the figure is used and the gate circuit 28 is closed at the intermusic part, etc., of an acoustic signal to record 0 on the recording medium 21 securely.
