で覆われていることを特徴とする磁気ヘッド。Consisting of a recording head section and a reproducing head section, the surface of each head section that contacts the recording medium is covered with a shielding member that exposes the area near the gap of the magnetic core and has a magnetic and electrical shielding effect. In the magnetic head, the shielding member is provided in a recessed portion formed on the surface of the magnetic core, leaving the exposed portion, and the recessed portion is located at a distance from the gap to one side of the exposed portion parallel to the gap. A magnetic head characterized in that the depths are substantially equal, the shield member has a thickness that is approximately half of the recessed portion, and the surface thereof is covered with a wear-resistant protective member.
