Abstract
A magnetic transducer includes sendust center core having an opening and a head gap extending from the opening to one side of the center core, and a pair of reinforcing cores. Each of the reinforcing cores includes a ferrite plate and a glass member mounted on one side of the ferrite plate. The center core is sandwiched between the two reinforcing cores such that the glass members are located on opposite sides, respectively, of the center core where the head gap is formed, and that one side of the center core is in flush with, or projects from, respective side faces of the glass member. The glass member is formed by a material having an abrasiveness resistivity which is smaller than that of said center core.
