Abstract

We have investigated writing properties of a single pole head with narrow track width for high track density recording. We have fabricated the single pole head whose main pole is made from Fe-Si-N film having Bs of as high as 1.9 T. The head was trimmed into narrow tack width using a focused ion beam system. The write properties of the head were evaluated using double layer media for perpendicular magnetic recording. Narrow track recording with a high resolution was demonstrated for a track width as narrow as 0.3 μm.
