Abstract: 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.

Abstract: A protruding rail portion is formed in the slider in a specific width. The core assembly in the specific width is fixed at the trailing side of the protruding rail portion. The ABS surface is formed in the specific width by the protruding rail portion and the core assembly. Since the ABS surface on the trailing side is formed only by the core assembly, the wear resistance is high and wearing is even. The assembling of the core assembly is simple because the core assembly can be set from the side direction of the slider.
