Abstract

PURPOSE:To simplify the constitution, to make small the size and to make low in the manufacture cost, by using a part of the shield case as the pole piece of the erasing head, in the magnetic head of composite type containing the recording and reproducing head and the erasing head in the same shield case. CONSTITUTION:In the magnetic head of composite type containing the recording and reproducing head 15 and the erasing head 19 in the same shield case 16, the cut-notch 16b is formed at a part of the side of the shield case 16, the peripheral of the window 16a is fitted to the common pole piece 11 via the air gap 17, the erase head 19 is constituted by winding the coil 18 at the cut-notch 16b, taking the peripheral of the window 16a and the fitting surface of the pole piece 11 into the tape slide surface at the erase head 19. Thus, a part of the shield case 16 is used as the pole piece of the erase head 19 to simplify the constitution.
