摘要： A first trench sidewall has a continuous first taper angle that terminates at a first plane. At least one layer may be deposited that forms a second trench sidewall with a continuous second taper angle that extends a predetermined depth past the first plane and is less than the first taper angle. A write pole may then be formed on the second trench sidewall with the write pole being closer to the first trench sidewall at the predetermined depth than at the first plane.

摘要： A magnetic writer includes a write pole configured such that the easy magnetic axis is parallel to the vertical length direction of the write pole tip and to the ABS of the recording media. The write pole tip can be a multilayer structure comprising alternating magnetic and nonmagnetic layers with a planar orientation substantially perpendicular to the ABS and with magnetic anisotropy parallel to the vertical length direction of the write pole tip. The alternating magnetic and nonmagnetic layers may be formed by electroplating on a conformal seedlayer in a trench, or by static off axis physical vapor deposition.

摘要： A magnetic device includes a write element having a write element tip and is operable to generate a first field at the write element tip. A conductor is proximate the write element tip for carrying a current to generate a second field that augments the first field. An encapsulating layer is on at least one surface of the conductor, wherein the encapsulating layer is made of a material that increases a maximum sustainable current density of the conductor to greater than about 108 A/cm2.
