发明名称 Thin-film magnetic head with inductive write head element
摘要 A thin-film magnetic head includes an insulation gap, a pair of yoke layers with one ends and the other ends, respectively, the one ends constituting magnetic poles separated with each other by the insulation gap, the other ends being magnetically coupled with each other, a coil conductor wound around at least one of the pair of yoke layers, first and second trace conductors with one ends electrically connected to both ends of the coil conductor, respectively, and first and second connection bumps electrically connected to the other ends of the first and second trace conductors, respectively. The first trace conductor includes a lower conductor layer and an upper conductor layer connected in parallel with each other, the second trace conductor including a lower conductor layer and an upper conductor layer connected in parallel with each other. The upper conductor layer of the first trace conductor and the lower conductor layer of the second trace conductor are arranged from top to bottom to face to each other. The upper conductor layer of the second trace conductor and the lower conductor layer of the first trace conductor are arranged from top to bottom to face to each other.
