Abstract

PURPOSE:To obtain a magnetic head which can perform the high-density recording by setting the distance from the gap to the core rear edge to the value within a fixed range for the surface of the magnetic head opposing to the magnetic recording medium. CONSTITUTION:For the circular magnetic head core composed of the sintered oxide ferromagnetic substance and consisting of trailing block 4', leading block 5 and back bar 7 wound with coil 8, width l' in medium running direction 3 of block 4' at the area opposing to the surface of magnetic medium is set to 0.5-2 times as longer as gap length G. Furthermore, the stage error is secured so that vertical length h from the surface opposing to the magnetic medium surface may be about 1 to several times as longer as gap length G. In such way, the magnetic head is formed.
