ABSTRACT:
In a magnetic head, a core half having a coil wound thereon and a core half having no coil wound thereon are disposed in abutting relationship with each other to form a magnetic gap. A projected portion is provided on a part of one core half in order to reduce the amount of induced noise produced in the coil by a noise magnetic flux entering from the front of the magnetic gap. The core half having a coil wound thereon and belonging to one magnetic head element and the core half having no coil wound thereon and belonging to another magnetic head element are opposed to each other to provide a compact multi-element magnetic head having reduced induced noise. Further, the magnetic head elements in the multi-element magnetic head present a minimum amount of induced noise for the noise magnetic flux entering from the front of the magnetic gap.
