Abstract

PURPOSE:To obtain a magnetic head of mechanical strength, by connecting a back core part, provided with head winding, to a front core joined with a nonmagnetic block with a magnetic gap. CONSTITUTION:Ingot 10 of a magnetic material, such as sendust, obtained by cutting a raw material is solder 12 to block 11 of a nonmagnetic material such as brass. Gap counter surface 13 is finished flat by being lapped. In sendust part 13, magnetic core window 14 is made by work. On the gap counter surface, SiO2 is formed by sputtering, etc., to a thickness half the gap length. Two block bodies are soldered 16 together by nonmagnetic material part 11 to form gap 17. Then, this block is cut to prescribed track width (l), back core junction surface 18 is lapped and back core 21 equipped with winding 22 is bonded with resin, glass, etc. Thus, the magnetic head of mechanical strength can be obtained.
