Abstract
PURPOSE: To obtain a high-precision narrow-track-width head easily by forming the front gap of a thin-plate core of an magnetic alloy of high magnetic permeability by using a nonmagnetic metal and by forming the rear gap by sticking and holding a self-welded core on a nonmagnetic material substance of wear resistance.
CONSTITUTION: Thin-plate blocks 14A and 14B, made of an Fe-Al-Si alloy of high magnetic permeability to a thickness of ≤25μ, are butted together to a size of 0.2W 0.6μ with a nonmagnetic metal interposed to form gap part 15 and the upper and lower of gap part 15 are welded by themselves to form block body 14. Next, block body 14 is sliced along X1, X2... to obtain thin-piece core materials 16 with gap length Gl. Each material 16, after being polished to a prescribed thickness of ≤25μ with precision, fixed to nonmagnetic support 17 of ceramics, etc., by adhesives. Next, winding window 18 is made to form tape slide surface 19. Thus, the gap part and track width are worked with high precision. Support 17 improves resistance to wear.
