Abstract:
A thin film magnetic head including:a substrate, a top magnetic layer and a bottom magnetic layer magnetically coupled to each other and having respectively a top pole tip and a bottom pole tip which face each other with a gap layer in between in part close to a recording-medium-facing surface facing a recording medium, a thin film coil provided between the top magnetic layer and the bottom magnetic layer, and an insulating layer for insulating the thin film coil from the top magnetic layer and the bottom magnetic layer, the top magnetic layer having a top pole which is magnetically coupled to the top pole tip and is separately formed from the top pole tip so as to extend to an area in which the thin film coil is formed, the top magnetic layer being located away from the substrate and the bottom magnetic layer being located closer to the substrate relative to the top magnetic layer, wherein a nonmagnetic area is formed in the top pole tip of the top magnetic layer, the nonmagnetic area including a hole and a nonmagnetic body buried in the hole.
