ABSTRACT:
A magnetic head is manufactured by the steps of accommodating a core chip blank into an elongated hole provided in a slider blank, joining the core chip blank and the slider blank together with glass and then grinding the surface to form a surface which makes sliding-contact with a recording medium. Glass for joining the core chip blank and the slider blank together is obtained by melting a glass rod mounted in a predetermined position on the slider blank. In order to prevent the core chip from being positionally moved by surface tension of the molten glass when the glass rod is melted, the edges of the elongated hole are partially provided with protrusions for positioning the glass rod so as to prevent surface tension of the molten glass from positionally moving the core chip.
