Abstract

PURPOSE:To establish the magnetic head suitable, by using the core constituting magnetic gap for the high density magnetic recording medium having greater anti- magnetism by forming it with the material having greater saturated magnetic flux than other core part. CONSTITUTION:A plurality of concave notches are formed at the chip tip correspondence sections t1,t2 of the ferrite pieces A,B (grooves S1,S2 for winding are provided for A) and the bottom (b), and the sendust (consisting of Fe-Si-Al alloy and having greater saturated magnetic flux than ferrite) is coated to the said concave notch, and this is polished so that the same plane is obtained as the ferrite surface. Next, after the gap forming material (e.g., SiO2) is coated on the entire surface of the head gap, the ferrite pieces A,B are fusion-bonded with low melting point glass, cutting is made at the parts shown in dotted lines to obtain respective magnetic heads.
