Perpendicular Magnetic Write head and method of manufacturing the same |
摘要 |
A perpendicular magnetic write head includes: a magnetic pole; a pair of nonmagnetic side gap layers provided on both sides in a track-width direction of the magnetic pole; a nonmagnetic trailing gap layer provided on a trailing side of the magnetic pole; a magnetic shield layer so provided as to surround the magnetic pole with both of the nonmagnetic side gap layer and the nonmagnetic trailing gap layer in between; and a magnetic seed layer formed between the nonmagnetic trailing gap layer and the magnetic shield layer, and having a saturation magnetic flux density higher than that of the magnetic shield layer. The magnetic seed layer is not formed between the nonmagnetic side gap layer and the magnetic shield layer. |
