More Information
Summary:An electrically non-conductive Al O -TiC thin film computer head substrate, exhibiting improved edge retention during precision machining, is formed from a mixture of Al O and TiC, where the TiC content in the final microstructure is less than 18 weight percent and which is produced from TiC having a surface to volume mean diameter of 2-10 micrometers. A thin film computer head substrate made from such a material, and sliders incorporating the substrate, exhibit significantly improved surface stability and diceability due to the exclusion of third-phase thermally-elastically mismatched dispersoids.
