A magnetic head having a pair of magnetic core halves integrally bonded to each other, each magnetic core half being formed by a single-crystal ferrite piece and a polycrystal ferrite piece bonded together to constitute a junction ferrite, with a magnetic gap being defined between abutting surfaces of the magnetic core halves. The single-crystal ferrite pieces are arranged towards the abutting surfaces of the magnetic core halves and the polycrystal ferrite pieces are arranged on the opposite side of the abutting surfaces with respect to the single-crystal ferrite pieces. Preferably, the surface of the single-crystal ferrite piece having sliding contact with the magnetic recording medium, the gap surface of the single-crystal ferrite piece and the surface of the single-crystal ferrite piece corresponding to the lateral surface of the magnetic head are the (211) plane, (111) plane and the (110) plane, respectively. The directions of the &lang&100&rang& crystal axes within the plane (100) are symmetrical to each other on both sides of the magnetic gap. The magnetic head is low in sliding noise and superior in electro-magnetic conversion characteristics. In addition, the magnetic recording medium is superior in abrasion characteristics since the partial advancing abrasion is prohibited from occurring on its surface configured to have sliding contact with the magnetic recording medium. <IMAGE> |
