Abstract
PURPOSE:To reduce the effect of external noise by arranging two magnetic heads in the slide direction side by side and winding a coil to the entire magnetic head without passing through the coil to the internal winding slot in addition to the normal winding the coil around the outer head core or winding the coil to both the magnetic heads entirely. CONSTITUTION:Two magnetic heads 11, 11 with different azimuth and horizontally symmetry are arranged closely side by side in the slide direction, the winding similar to the double azimuth head is applied and the coil 15 does not pass through the internal winding slot 17 and the coil is wound to both the magnetic heads 11, 11 entirely. Then the coil 15 is wound to both the magnetic heads 11, 11 entirely in a direction causing a magnetic field in a direction opposite to the magnetic field induced by the coil 15 wound around the outer side head core 16 between the inner winding slot 17 and the outer winding slot 18 not through the inner winding slot 17 by nearly 1/2 of the winding turn around the outer head core 16 between the internal winding slot 17 and the external winding slot 18. Thus, the effect of external noise caused by the unrealization of the cross section ratio of the outer head core 16 and the inner head core 14 and the turn ratio of the coils inversely proportional thereto is reduced.
