Abstract:
Magnetic head comprising:a solid substrate; a magnetic circuit including first and second polar parts positioned side by side along a plane parallel to a surface of the substrate and separated by a non-magnetic air gap; and a conductor coil surrounding a part of the magnetic circuit no portion of which is embedded in the substrate, wherein at least one of the first and second polar parts form that part of the magnetic circuit no portion of which is embedded in the substrate, and the conductor coil surrounds the at least one of said first and second polar parts no portion of which is embedded in the substrate, and the conductor coil comprises a lower sheet of conductors passing under the at least one of the polar parts and is embedded in the substrate on one side of the substrate without exposing said lower sheet of the conductor on an opposite side of the substrate, and an upper sheet of conductors is astride the at least one of the polar parts.
