Pole design optimization of shielded planar writer for 2   Tbit / in 2 recording

A shielded planar head with a multi-step-tapered main pole assuming ion-beam milling fabrication was studied to obtain a large recording field along with suppressed fringing field. The head main pole with a three-step-tapered structure was optimized in terms of the top, main, and bottom slope angles...

Summary:A shielded planar head with a multi-step-tapered main pole assuming ion-beam milling fabrication was studied to obtain a large recording field along with suppressed fringing field. The head main pole with a three-step-tapered structure was optimized in terms of the top, main, and bottom slope angles. The optimized head showed a remarkably suppressed fringing field compared with a conventional single-step-tapered pole head. The recording simulation suggests that the head has the potential for 2   Tbit / in 2 recording in combination with a bit patterned medium.
