Magnetic cores for transducing heads made of manganese/zinc ferrite pole pieces defining a glass-filled transducing gap may be etched in hydrofluoric acid without excessive etching of the glass. The etching process reveals the ferrite grain structure to promote adhesion of a subsequent overcoating.
