CCP-CPP-GMR HEAD ASSEMBLY, MAGNETIC RECORDING/REPRODUCING APPARATUS, AND SPECIFICATION METHOD OF APPROPRIATE SENSE CURRENT DIRECTION OF CCP-CPP-GMR HEAD |
摘要 |
Disclosed is a CCP-CPP-GMR head assembly which has: a CCP-CPP-GMR head that includes at least a current control layer having as a microstructure a plurality of truncated cone electric conductors with axes the same as a current direction and an insulator filling between the plurality of truncated cone electric conductors, and in which a surface on which a larger-area basal plane of the plurality of truncated cone electric conductors is greater in number is a first surface of the current control layer and a surface of an opposite side of the first surface is a second surface of the current control layer; and a sense current source providing the CCP-CPP-GMR head with a sense current that flows from the second surface to the first surface, a magnetic recording/reproducing apparatus having such a head, and a specification method of an appropriate sense current direction of the CCP-CPP-GMR head.
