。[Claims for Utility Model Registration] (1) Two first and second magnetic poles electrically connected via a center tap to a main magnetic pole or an auxiliary magnetic pole arranged perpendicularly to a perpendicular magnetic recording medium. In a perpendicular magnetic head that is wound with windings and performs magnetic recording and reproduction with the perpendicular magnetic recording medium through the two wound windings, the first and second windings are connected to each other for each winding. A perpendicular magnetic head characterized in that the magnetic head is separated into two parts and wound around the main magnetic pole or the auxiliary magnetic pole. (2) The perpendicular magnetic head according to claim 1, wherein the first and second windings are separated in a direction perpendicular to the perpendicular magnetic recording medium. (3) The vertical magnetic head according to claim 1, wherein the first and second windings are laminated and separated in a concentric manner. (4) Among the first and second windings, the outer winding has a lower conductor resistance than the inner winding, as described in claim (3) of the utility model registration. Vertical magnetic head. (5) The vertical magnetic head according to claim 3, wherein the winding wound on the outside has a larger wire diameter than the winding wound on the inside. (6) The vertical magnetic head according to claim 3, wherein the outer winding has a larger wire diameter and a smaller number of turns than the inner winding.
