Excellent performance of laminated Fe-Si-Al alloy film heads is demonstrated in applications to high-definition VCR and to digital recording. It is emphasized that these results are derived not only from the ring-shaped core geometry but also from the isotropic behavior in the magnetic properties of the sputtered Fe-Si-Al alloy films. The experimental results on the isotropic magnetic behavior are summarized. A mass-production process for the laminated alloy film heads is introduced, emphasizing the importance of stacked bar fabrication steps
