Readback Performance of Single-pole Head with Fe-Si-N Main-pole

Abstract

In Fe-SiN films, the nitrogen content and the double-layered construction improve the soft-magnetic properties and the domain structures. The readback output of the Fe-SiN single-pole head increases and the head noise is induced with increasing the nitrogen content. On the other hand, the Fe-Si-N/SiOz double-layered head shows extreme output deterioration. These phenomena are related to the stress anisotropy.
