Abstract:
A method according to one embodiment includes contacting an oxidant with an AlTiC portion of a magnetic head for recessing TiC grains of the AlTiC portion. A method according to another embodiment includes contacting a peroxide with an AlTiC portion of a magnetic head for recessing TiC grains of the AlTiC portion from a media bearing surface of the AlTiC portion. A magnetic head according to yet another embodiment includes an AlTiC portion having a media bearing surface; and a thin film portion coupled to the AlTiC portion, wherein TiC grains of the AlTiC portion are recessed from the media bearing surface.
