ABSTRACT:
A retrieval signal recording apparatus for magnetic recording/reproducing apparatus wherein when an information signal is recorded on a magnetic tape, a retrieval signal different from the information signal is recorded at the beginning of the recorded information signal so that the magnetic tape is stopped or made in the reproducing mode just when the retrieval signal is picked up from the tape under a high tape speed. In the retrieval signal recording apparatus, the retrieval signal is recorded for a certain time only at the beginning of recording the signal or at both the beginning and end of the recorded signal, and the recording time of the retrieval signal is changed in accordance with the switching of a plurality of tape speeds such that the length of the retrieval signal recorded on the magnetic tape is made substantially constant even if the tape speed is different.
