Abstract
The recording characteristics and wide-band playback characteristics of laminated heads composed of Co-base superstructured nitride alloy films were investigated. The superstructured alloy film was composed of 250 Ã… thick nonnitride and nitride layers of Co-Nb-Zr, and had higher thermal stability, higher saturation flux density, and higher initial permeability at high frequencies than does conventional Co-Nb-Ta-Zr amorphous alloy film. Because of these excellent properties, excellent recording performance and wide-band playback characteristics were achieved for laminated heads with narrow gap lengths.
