Abstract
PURPOSE:To lower resistance in a conductor coil and to reduce a head noise, by forming one winding of the innermost periphery in the plane shape of the conductor coil in egg shape, and one winding of the outermost periphery in shape similar to a rectangle with roundness. CONSTITUTION:Six turns of the conductor coil 1 of one layer are wound spirally in the periphery of a back gap 4 passing through both magnetic films 2 and 3. In such a case, by forming the plane shape of one winding on the innermost periphery of the spiral conductor coil 1 in the egg shape, it is possible to minimize the size of the back gap 4 and an electrical contact as far as possible, and to extend an area where the conductor coil 1 can be formed to the inside. Also, by forming one winding on the outermost periphery in the plane shape similar to the rectangle with the roundness, it is possible to prevent the length of the conductor coil from being extended waste-fully and also to utilize even the outside of the area where the conductor coil 1 can be formed. Since the cross-sectional area of the the conductor coil can be increased by the above functions, the resistance in the conductor coil can be lowered, and as a result, the head noise can be reduced.
