Abstract
PURPOSE: To form narrow gaps readily with good accuracy and enable abrasion resistance of heads to be made by forming a non-ferromagnetic metal layer which becomes an operating gap through electroplating and binding the same with other core material and amorphous alloy layer.
CONSTITUTION: An amorphous alloy layer 3 is electroplated on the gap face 2 of a head chip 1 and its neighborhood and is then polished in approximately parallel with the face 2, whereby a gap forming face 4 is obtained. Next, a non-ferromagnetic metal (alloy) layer 5 is electroplated to the thickness corresponding to an operating gap 6 on the face 4. Over this is electroplated an amorphous alloy layer 7 of the same composition as that of the layer 3, and a groove 10 is formed in opposition to the gap face 9 of the opposing head chip 8. Next, the chip 8 is fitted in the groove 10, and the amorphous alloy layer 11 is electroplated in continuation to the layer 7, whereby an integrated amorphous alloy layer 12 is obtained. Next, the layers 3, 5, 12 are polished and a magnetic head 14 having a tape running face 13 is produced. a suitable binding agent is filled in a back gap 15
