Abstract

PURPOSE: To prevent the deterioration of tape running characteristics by making a non-magnetic member of a magnetic tape facing portion of a material which is prepared by impregnating a tetrafluorine resin in a porous structure.
CONSTITUTION: The non-magnetic metal of a magnetic tape facing portion 22 is prepared by impregnating a tetraflourine resin in a molded porour structure such that the matiral is then subjected to oxidzing treatment, such that the material thus oxidized is converted into hard osidized aluminum, sch that the luminum thus condition of the hard oxidized aluminum, and such that the molded structure has its surface impregnated with the tetrafluorine resin. Thus, it is possiblle to esily form an integral stucture of a tape sliding side forming member 22 and to integrate this member 22 and a head core positioning member 222
