    摘要: A method for manufacturing a recording medium on a hard disk includes forming a data recording layer on the disk, forming a nitrogenated carbon overcoat layer over the data recording layer, (with or without intervening layers), and the processing data recording layer to protect it from the nitrogen used in the process of forming the nitrogenated carbon. In one approach, the step of processing the data recording layer is accomplished by forming a buffer layer between the data recording layer and the overcoat layer by depositing carbon on the data recording layer using a carbon deposition process excluding nitrogen, then forming the overcoat layer by depositing carbon on the buffer layer using a carbon deposition process that includes a nitrogen source. In an alternative, the step of processing the data recording layer is accomplished with or without a buffer layer in an automated process by transferring the disk after deposition of the data recording layer into an isolation chamber that has no nitrogen, and then into a nitrogenated carbon deposition chamber thereby preventing contamination of the data recording layer deposition process by nitrogen used in the overcoat layer deposition step.

    摘要: A slider in a disk drive is shock-protected with an overcoat layer of either metal or polymer directly on the areas of the slider that are prone to contact the disk when the slider is loaded off the platform, or when the slider is shocked while in operation over the data zone of the disk. The material used to form the layer absorbs shock and reduces wear, and is bonded or sputtered to the head in a region other than the pads of the air bearing surface. This region is typically the reactive ion etched (RIE) surface area and is slightly below the pads of the air bearing surface of the head. In an alternate version of the invention, the slider is protected by covering only the edges of the slider with a suitable material. Finally, the entire slider may be encased with the overcoating except for the pads of the air bearing surface.
