摘要: A silicon nitride self-lubricating layer forms the upper surface of a data storage device, such as a rotating disk or a non-rotating memory device, e.g., a credit card-type memory device using a memory strip. The silicon nitride self-lubricating layer can replace the carbon protective overcoat and liquid lubricant used in conventional data storage devices. The silicon nitride self-lubrication layer provides the desired lubrication and protection between the slider and the data storage device. The silicon nitride layer also will not evaporate under high temperatures found in an optical data storage system. In addition, a data storage device may include a plastic polymer layer over which an iron oxide material is deposited. The use of a plastic polymer layer and iron oxide recording layer is particularly advantageous because a low temperature deposition process can be used with the iron oxide material.

摘要: 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.
