Abstract
PURPOSE: To improve operation efficiency with the defective rate of a winding process lowered by forming an insulating coating, whose thickness is great at the corner part of a magnetic head core, on the coil winding part of the magnetic head core.
CONSTITUTION: In a working process for core chip CP consisting of work gap 1, side gaps 2 and 3 charged with a glas material, winding groove 4, etc., corner parts (a) to (d), and (a') to (d') of passages P and Q provided with winding are made acute, so that the insulating coating part of the winding may be broken in winding. To prevent this, an insulating coating of SiO2, etc., is provided by a chemical vapor-deposition method, etc., so that corner parts (a) to (d), and (a') and (d') will be thicker than other parts. In this way, the cutting action of corner parts are lessened effectively, so that the defective rate of the winding process will lower.
