切り換える検出手段とを設けてなる磁気録画再生装置。Video signals are recorded on diagonal tracks on the magnetic tape, and a pilot signal with a frequency different from that of the adjacent track is recorded for each track. In a magnetic recording/playback device that applies tracking servo by detecting crosstalk caused by a pilot signal recorded on a track, the pilot that should normally be recorded next to the last track when video signal recording is temporarily stopped during splice recording. recording means for recording the signal and a pilot signal for determining the final track having a different frequency; and detecting the pilot signal for determining the final track when the final track is reached while reproducing the recorded track. and detecting means for switching to recording from the next succeeding track.
