Abstract
A silicon nitride self-lubricating layer forms the upper surface of a data storage disk. The silicon nitride self-lubricating layer can replace the carbon protective overcoat and liquid lubricant used in conventional data storage devices in which an aerodynamic slider is supported by an air bearing by providing both physical protection for the underlying recording layer and lubrication between the slider and the disk.
