Abstract (in Japanese) (See Japanese page) 
(in English) Design of write head pole structure for thermally assisted magnetic recording was studied by head field calculation and recording simulation. For leading edge recording, the leading tapered pole structure combined with a leading shield provided increase in recording field while suppressing undesirable field peaks showing maximum head field strength. Narrowing field distribution in cross-track direction was also investigated. As a result, the developed head pole structure exhibited improved signal to nose ratio and decreased adjacent track erasure, and had a potential of 2.5 Tbit/in2 recording.
