  • Patent number: 7272883
    Abstract: In one illustrative example disclosed, a method for use in making a magnetic head involves forming a thermal-assist heater for the magnetic head; forming a plurality of coil layers of a write coil using a damascene process; and simultaneously forming an electrical connection to the thermal-assist heater in the same damascene process used to form the write coil. Advantageously, fabrication steps are reduced using a parallel process that provides for relatively small dimensions and reduces the possibility of electrical shorting. The method may be alternatively used to form an electrical connection to any other suitable electrical device for the magnetic head, such as an electrical lapping guide (ELG) or other component.
