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 detects crosstalk caused by a pilot signal recorded on a track and performs a tracking sabot, the pilot a recording means for recording a pilot signal for final track discrimination having a frequency different from that of the signal;
A magnetic recording/reproducing device comprising: detecting means for detecting a pilot signal for determining the final track when the final track is reached while reproducing recorded tracks, and switching to recording from the next succeeding track.
