摘要： A magnetic recording system which comprises a recording/reproducing head for effecting recording and reproduction of data with respect to one recording track formed on a magnetic tape, an erasing head disposed in side by side relation with respect to the head and secured thereto, for effecting erasing with respect to two tracks, i.e., the track traced by the recording/reproducing head and the next track, an auto-tracking circuit for compensating for the deviation of the position of the recording/reproducing head with respect to the start track for rerecording, and a switch control section for controlling the operation of the erasing head by causing switching of a switch circuit connected to the erasing head.
