A composite magnetic head including a record/playback gap and an erase gap comprises a straight central core, a pair of arcuate lateral cores having their ends disposed in opposing relationship with the opposite ends of the central core disposed therebetween, each of the lateral cores being formed with a bobbin carrying portion at its one end which extends in a direction perpendicular to the length of the central core, a bobbin having a central flange and a pair of flanges at the opposite ends, the central flange being formed with an opening for receiving the central core and the bobbin being formed with a slot extending through the entire length of the bobbin including the flanges at the opposite ends for receiving the lateral cores, the slot extending in a direction perpendicular to the opening which receives the central core, and a pair of coils disposed between the central flange and the respective end flanges, the central core and the lateral cores forming a record/playback gap and an erase head at their one end when the cores and the bobbin are assembled together by inserting the remote end of the central core into the opening and inserting one end of the lateral cores into the slot.
