ABSTRACT:
A composite magnetic head is integrally formed with a recording/reproducing head section having a recording/reproducing gap and an erasing head section having two erasing gaps. The magnetic head has formed in its surface facing a magnetic recording medium two parallel diagonal grooves extending across the two head sections which are inclined with respect to the gaps and spaced apart so as to define the outer ends of the recording/reproducing gap and respective inner ends of each of the erasing gaps.
