摘要： A method is provided for applying an overcoat to a slider and sensitive elements of a magnetic head which has improved coverage, reduced spacing loss and improved corrosion resistance. After lapping, an overcoat material is sputter deposited on the air bearing surface (ABS) of the slider, followed by a step of sputter etching the overcoat. The sputter etching redeposits material from high points on the slider and fills in trenches formed during the lapping process. The redeposition of the overcoat from the high places to the low places of the slider decreases the overall thickness of the overcoat, thereby decreasing spacing loss. The filling of the trenches implements increased coverage which increases wear resistance of the slider and more adequately protects the sensitive elements of the magnetic head from corrosion. In a preferred embodiment, a portion of the overcoat is left on the high places to ensure that the sputter etching does not damage the sensitive elements of the magnetic head. If the overcoat is completely etched from the high places an optional second overcoat may be applied which is thinner than the first overcoat. This method may also be applied to other articles such as a magnetic disk.
摘要翻译：提供了一种将外涂层施加到滑块和磁头的敏感元件的方法，其具有改进的覆盖范围，减小的间隔损耗和改善的耐腐蚀性。研磨后，将外涂层材料溅射沉积在滑块的空气轴承表面（ABS）上，随后溅射蚀刻外涂层。溅射蚀刻从滑块上的高点重新沉积材料，并填充研磨过程中形成的沟槽。外涂层从滑块的高处重新沉积到滑块的低处降低了外涂层的总厚度，从而减小了间隔损耗。沟槽的填充实现增加的覆盖，增加滑块的耐磨性，并更充分地保护磁头的敏感元件不被腐蚀。在优选实施例中，外涂层的一部分留在高处，以确保溅射蚀刻不会损坏磁头的敏感元件。如果外涂层从高处完全蚀刻，则可以施加比第一外涂层更薄的任选的第二外涂层。该方法也可以应用于诸如磁盘的其它物品。

摘要： A single layer wear coating is provided for a magnetic head assembly. The single layer is silicon or silicon-based material with a thickness in the range of 30-75 .ANG.. The single layer may be formed by a single step of deposition employing a DC magnetron. The single layer wear coating improves the wear performance of the magnetic head assembly and protects one or more sensitive elements of a magnetic head without significant reduction of spacing loss.

摘要： A silicon coating on an air bearing surface for magnetic thin film heads. A thick silicon layer is provided to replace metallic layers such as TiW as an overcoat for thin film heads. The silicon layer will provide a durable head-disk interface and act as a reflective surface for fly height measurement. The silicon layer can be planarized with the pole tips to avoid any magnetic spacing loss. The thickness of the silicon coating is preferably between 125 and 6500 angstroms thick. The slider body may be fabricated from silicon such that the silicon coating is substantially identical to the silicon slider body, thereby preventing thermal mismatch therebetween. The silicon coating is preferably applied using a magnetron sputtering technique which provides a high rate of deposition of silicon to form a dense, low stress silicon layer.

摘要： We disclose a bi-layer wear pad, for use in a slider/magnetic media interface, comprising a wear layer and an adhesion layer. The wear material is either carbon or a carbonaceous material. Typical carbonaceous materials useful for wear layers include elements such as hydrogen, fluorine, nitrogen, boron, and silicon dioxide. The adhesion layer is a thin cermet such as nichrome oxide (NiCrOx) or chromium silicon oxide (CrSiOx). Use of the cermet adhesion layer allows a relatively thick wear layer to be deposited with good adhesion and superior durability.
