Abstract (in Japanese) (See Japanese page) 
(in English) Observation of in-plane domain structure of writer pole for perpendicular recording head was performed by electron holography in order to investigate the cause of pole erasure concerned to the instability of domain state. As a result, it was found that the stability of domain structure relates to the domain wall trapping, and the pole erasure can be suppressed by the stable domain structures.
