“…On the other hand, it is known that the addition of nitrogen into the Fe-Si film improves the magnetic properties such as the permeability, the coercivity and the anisotropy without disturbing the decrease of the saturation magnetization [1]. However we have already confirmed that the head noise is induced in a single-pole head with the Fe-Si-N main-pole [2].…”

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

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.
