Abstract
A magnetic head includes a core chip, a slider having an aperture for receiving the core chip and protrusions for positioning and constraining the core chip received in the aperture. The protrusions are formed on the inner walls of the aperture. After the core chip has been inserted into the aperture, a molten welding material is flowed into the clearance between the core chip and the inner walls of the aperture so as to weld the core chip to the inner walls of the aperture in the slider. The clearance between the core chip and the inner walls of the aperture is equalized. If the core chip is formed of soft magnetic material, the slider can absorb electromagnetic noises.
