Abstract
PURPOSE: To prevent magnetic characteristics from deteriorating by simplifying fabrication by welding at least partition plates and a core, among the core wound with a coil, shield plates and partition plates, in one.
CONSTITUTION: After core 10 wound with coil 9 and partition plates 11 and 11a insulating magnetically core 10 from shield plate 12 and adjusting the track position of core 10 are stacked, welded part 13 is welded by irradiating with laser beam, etc., to obtain unit 8 in the body. Unit 8 can be built in core support 14a easily and rapidly and never deforms even if external force is applied. As a substitute for partition plate 11a, a spring can be arranged. When the sprint is used, core 10 and partition plate 11 are only welded. Two head half bodies 17 obtained in this way are aligned to manufacture a magnetic head. Since no adhesive is used to fix core 10 and partition plate 11, deterioration of characteristics due to strain and size variance caused by the hardening of the adhesive and elapse variation can be prevented, and the generation of defective products can also be reduced.
