MAGNETIC HEAD HAVING POLYCRYSTALLINE COATING
First Claim
1. A magnetic head, comprising:
- a substrate;
an array of transducers formed on the substrate, wherein the transducers and substrate form portions of a magnetic media facing surface; and
an at least partially polycrystalline dielectric layer on the media facing surface,wherein the at least partially polycrystalline dielectric layer is on a magnetic film of at least one of the transducers in the array.

Abstract
A magnetic head according to one embodiment includes a substrate; an array of transducers formed on the substrate, wherein the transducers and substrate form portions of a magnetic media facing surface; and an at least partially polycrystalline dielectric layer on the media facing surface, wherein the at least partially polycrystalline dielectric layer is on a magnetic film of at least one of the transducers in the array. A method for forming an at least partially polycrystalline dielectric layer on a media facing surface of a magnetic head according to one embodiment includes forming an at least partially polycrystalline dielectric layer on an array of transducers of a magnetic head, wherein an oxide layer is formed above at least some of the magnetic layers before and/or during the forming of the at least partially polycrystalline dielectric layer.
