Abstract

The laminate film with amorphous Co based Co-Zr-Ta (80-4-16 wt%) alloy film and alumna layer which was mechanically soft was incorporated into the write head, which recesses the laminate film from ABS. It was shown that the writer with the laminate yoke shows a single magnetic domain yoke, and shows significantly enhanced inductance bandwidth
