Abstract
A method for manufacturing thin film magnetic media disks entailing the improvement arising from causing spaced electrical probes to engage spaced portions of an exposed outer surface of a disk overcoat layer; creating a voltage across the spaced electrodes; measuring a function of electrical resistance between the ends of the probes in engagement with the exposed outer surface of the overcoat layer; and employing this measured resistance function generally as a measure of wear properties of the overcoat layer.
