Abstract

PURPOSE:To achieve the realization of high-density recording and high-sensitivity reproduction by using single crystal ferrite to head chips, setting the faces opposing to recording faces at crystal face 110, setting gap opposing faces at a specific angle to crystal face bearing 110 and forming back cores with polycrystalline ferrite.
