In a magnetic head including a recording and reproducing magnetic core having a transducing gap at an intermediate position and a pair of erasing magnetic cores arranged on respective sides of the recording and reproducing magnetic core so as to straddle the same, thereby forming erasing gaps between the erasing cores and the recording and reproducing magnetic core, respectively, a difficulty of causing an excessive DC magnetic bias to be applied along the length of the transducing gap is eliminated by forming a cut-away portion on a part of surface portion of each erasing magnetic core facing a magnetic recording medium and the transducing gap.
