A method for manufacturing a magnetic head core of a complex magnetic head includes binding a first core material of a U-shaped cross section and a second core material of a flat plate shape to form a tubular core material having two bonded portions between the first and second core materials. Then a plurality of grooves are formed in the tubular core material across one of the bonded portions to form a plurality of track surfaces. The grooves are then filled with a fused glass material, and the other of the bonded portions is removed to form a substantially U-shaped core block having a plurality of track surfaces separated by the glass-filled grooves. The U-shaped core block is then sliced along each of the grooves to obtain a plurality of magnetic head cores. A complex magnetic head manufactured by the method is also disclosed.
