Abstract:
1. A thin-film magnetic head comprising: an insulation gap; a pair of yoke layers with one ends and the other ends, respectively, said one ends constituting magnetic poles separated with each other by said insulation gap, said the other ends being magnetically coupled with each other; a coil conductor wound around at least one of said pair of yoke layers; first and second trace conductors with one ends electrically connected to both ends of said coil conductor, respectively; and first and second connection bumps electrically connected to the other ends of said first and second trace conductors, respectively, said first trace conductor including a lower conductor layer and an upper conductor layer connected in parallel with each other, said second trace conductor including a lower conductor layer and an upper conductor layer connected in parallel with each other, said upper conductor layer of said first trace conductor and said lower conductor layer of said second trace conductor being arranged from top to bottom to face to each other, and said upper conductor layer of said second trace conductor and said lower conductor layer of said first trace conductor being arranged from top to bottom to face to each other.
