抄録

We have developed a Co-Ni-Fe write head with a short yoke length for high-speed recording. By reducing the yoke length to 9.5 μm, the eddy currents induced in a yoke with a relatively low resistivity (0.2 μΩm) were reduced. The head of this short yoke had good write performance for a medium with a coercivity of 400 kA/m (5000 Oe) at frequencies up to 250 MHz (the overwrite less than - 30 dB, and nonlinear transition shift less than 7%).
