METHOD FOR MAKING MAGNETIC HEAD COMPOSED OF FERRITE

A method for making a circular magnetic head having at least two head members composed of ferrite and an effective gap between the members, each of the members having at least one gap surface. The gap surface on each of the head core members is first polished, and then a glass powder layer is adhered to the polished gap surface of one of the head members. The glass powder layer is fixed at a glass layer forming temperature to form a glass layer which adheres to the polished gap surface and which has a thickness substantially equal to the desired gap dimension. The one head member is then joined to the other head core member at the polished gap surface. A piece of glass having a softening temperature lower than that of the glass layer is placed on the joint area of the two head core members at the surface opposite to the head surface and the two joined head members are fired at a temperature lower than the glass layer forming temperature to melt the piece of glass, whereby the melted piece of glass acts, upon hardening, as a bonding agent for the two joined head members.
