Abstract
A cusp-field single-pole (CF-SPT) head and perpendicular double-layered media were examined by using sputtered Fe-Co-Al-O/Ni-Fe films with excellent soft magnetic properties in a wide range of film thicknesses. The CF-SPT head with a high Bs Fe-Co-Al-O main pole of 2.4Â T shows a better overwrite property than that with a lower Bs Fe-Si-N main pole of 1.9Â T. The medium with a high Bs Fe-Co-Al-O soft magnetic underlayer (SUL) had a lower transition noise, and consequently a higher SNR than that with a lower Bs Fe-Si and Ni-Fe-Nb SUL. Furthermore, it also shows good write sensitivity and overwrite property.
