ABSTRACT:
A magnetic recording-reproducing apparatus in which one of the speeds at which a magnetic tape is made to run during the recording or reproducing mode is selectively preset. During the recording mode, a cue signal having a lower frequency than a recorded sound signal is recorded on a magnetic tape together with a desired sound signal. During the fast forward or rewind mode, the cue signal is detected, thereby making it possible to indicate the desired sound signal. This cue signal has a frequency proportionate to the speed at which the magnetic tape is made to run during the recording mode, and is recorded on the magnetic tape for a length of time inversely proportionate to the running speed of the magnetic tape.
