Abstract
PURPOSE: To manufacture a magnetic head case easily at low cost by bringing a substance with resistance to wear into contact with a concave part provided to the front face of a case made of a substance of high magnetic permeability and by welding the resistance-to-wear substance to the substance of high magnetic permeability of the concave part.
CONSTITUTION: Case 3 made of a substance of high magnetic permeability such as permalloy is provided with opening part 3a through which a core not shown in the figure is exposed and concave part 3b where sliding plate 4 is fitted; and depth (d) of concave part (b) is made nearly equal to thickness (t) of plate 4 and convex part 3c is formed in concave part 3b. Plate 4 is formed of the same substance with resistance to wear as that of the above-mentioned core. When electric power is supplied from electric power source 6 with case 3 and plate 4 contact-held between electrodes 5a and 5b, current density near convex part 3c provided in concave part 3b is increased and the substance near convex part 3c is melted by Joule heat, thereby spot-welding case 3 and plate 4.
