Research output: Contribution to journalArticlepeer-review


In order to achieve high linear density recording, an SPT (single pole type) head must be used with a thin main pole film. We confirmed that high resolution in reproduction is obtained by using a head with a main pole 0.1 µm in thickness, but found that the reproduced properties become worse when the head is less than 0.1 µm thick. We also found that these properties are closely related to the cross-tie domain wall structure.
