Abstract
In a cue recording system for a tape recorder, an audio signal is recorded by a first recording section on a first track of a tape. In a second recording section, a cue signal is superposed on the audio signal. The composite signal formed of the audio and cue signals is then recorded on the second track of the tape. In the playback mode, the audio signal and the cue signal recorded on the second track are separated by a filter. When the separated second-track audio signal is mixed with a first-track reproduced output, the resultant audio signal has substantially the same low-frequency response characteristic as a stereo head system, and a same S/N ratio as the monaural head system. An insufficient low-frequency response of the second track is compensated by the flat frequency response of the first track. Degradation of the S/N ratio of the signal of the first track can be improved by the mid or higher frequency component of the audio signal of the second track.
