摘要：
A coil encircling the ferrite core of a magnetic head attached to a slider used in a hard disk drive is formed using two mating chips. A first chip having layered wires and bonding bumps is inserted in the winding window between the ferrite core and the body of the slider. A second chip having layered wires, bonding bumps and a groove straddling the ferrite core is disposed outside the winding window and mates with the first chip. Bonding bumps, comprising low-melting solder, are heat bonded to form a continuous coil.
