Write pole fabricated using a carbon hard mask and method of making

摘要

A magnetic writer comprises a write pole, a substrate and a non-magnetic, oxygen-free buffer material. The write pole has a leading edge, a trailing edge, a first side and second side. The substrate is at the leading edge of the write pole. The non-magnetic, oxygen-free buffer material is located between the write pole and the substrate, and the oxygen-free buffer material is selected from Re, Ru, Os, Rh, Ir, and combinations thereof.

1. A magnetic writer comprising:
a write pole having a trapezoidal shape, a leading edge side, a trailing edge side, a first side and a second side, the write pole having a width of less than about 100 nanometers and a wall angle greater than about 7 degrees from vertical; a substrate at the leading edge side of the write pole; and a non-magnetic, oxygen-free buffer material located between the write pole and the substrate, the oxygen-free buffer material comprises Re, Ru, Os, Rh, Ir, or combinations thereof.
