Abstract

A three-dimensional (3-D) FEM simulation of a 1 Tbit/in² head/medium model has been carried out. Three new structures, side shields, a tapered main pole, and a tapered return path for the head have been introduced in order to produce a large recording field, a small stray field to the adjacent tracks, and a skew-effect-free field distribution, that are all indispensable for higher linear and higher track density recording. The proposed head structure gives sufficient head field strength and gradient for 1 Tbit/in² recording as described in previous literature, as well as a narrow pulse width.
