Abstract
We examined the write performance of heads with a CoNiFe /NiFe composite write pole. The saturation induction Bs of the CoNiFe film was 2.1 T (21 kG). The CoNiFe layer thickness was typically 0.5-0.6 μm; and the rest of the write pole was composed of Ni80Fe20. The dual high Bs layer structure with the CoNiFe films on both sides of the write gap gave excellent overwrite performance. It was over 30 dB for a medium that had a high coercivity of 560 kA/m (7.0 kOe).
