Abstract:
A method for manufacturing a magnetic head core of a complex magnetic head, comprising:bonding a first core of a U-shaped cross section and a second core of a flat plate shape to form a tubular core having first and second bonded portions between the first and second cores;forming a plurality of grooves in the tubular core across the first bonded portion to form a plurality of track surfaces;forming a chromium layer having a thickness of from 50 .mu.m to 300 .mu.m on surfaces of the plurality of grooves to expedite the fusion of a glass material thereto by improving wettability of the glass material;filling the chromium-coated grooves with the glass material and fusing the glass material;removing a portion of the bonded first and second cores, the portion including the second bonded portion to form a substantially U-shaped core block having a plurality of track surfaces separated by the grooves; andcutting the U-shaped core block along each of the grooves to form a plurality of magnetic head cores.
