Abstract

PURPOSE:To improve corrosion resistance of gap to bonding glass, improve its abrasion resistance and further controls the same to a fine and even desired length by providing specific ceramic films on the butt faces of core blocks. CONSTITUTION:After the butt faces 2, 2', 3, 3' of a pair of core blocks 1, 1' of U-shape in section such as of ferrite have been mirror-finished, they are evaporated with ceramics such as SiC, whereby the films 4, 4', 5, 5' of a thickness (t) slightly thinner than, e.g., 0.25mu, are formed. Next, the faces 2, 3, 2', 3' are mutually contacted and are held under a suitable pressure from the arrow directions. After placed with solder glass bars 6, 6, the blocks 1, 1' are heat-bonded. Next, the core block 8 having been bonded at the glass bonding part 7 is finished of the tape contact face like a dotted line and is sliced to a specified width W like two-dots-dash lines, whereby the magnetic head core 10 such as of 0.5mu in the length L and 40mu in depth D of the gap 9 is obtained.
