<p>A magnetic recording apparatus for recording a video signal in a helical scanning type video tape recorder along a recording track with a guard band between two adjacent recording tracks (TL1,TL2) in the long playing mode. The video signal and the audio signal are consecutively recorded on a relatively shallow layer portion and a relatively deep layer portion of the magnetic coating on the magnetic tape (13) by means of a rotary video head (L1,L2) and a rotary audio head (A1,A2) along respective recording tracks (TL1,TL2,TA1,TA2) which generally overlap each other. After the audio signal is recorded and prior to the recording of the video signal, the signals recorded on the relatively shallow layer portion of the magnetic coating on the magnetic tape are erased by a rotary video head (S1,S2) having a relatively large track width along a track (TS1,TS2) which includes both the video signal recording track for the long playing mode and the audio track.</p> |
