Abstract
An accelerated wear test procedure suitable far testing the durability of the hard disk overcoat in a quasi-contact head-disk interface oper ation mode has been investigated and applied to carbon overcoats with various amount of nitrogen incorporation. Strong correlations have bee n obtained among the wear test results, surface roughness and friction measurements. Carbon overcoats with a high level of nitrogen incorpor ation appear to be mast wear resistive.
