摘要:
A thin film magnetic head is able to control occurrence of Barkhausen noises attributable to configuration magnetic anisotropy of an upper shield layer. An inductive head is provided with a magnetic material layer having a space for forming a coil layer thereon. A very narrow gap is provided between a front separate layer that opposes a magnetic recording medium and a rear separate layer that opposes the front separate layer. The front separate layer serves also as an upper shield layer of an MR head and a lower core layer of the inductive head.
