Abstract: The invention relates to an improved high performance magnetic recording device. The recording device comprises a magnetic recording disk, a slider having a transducer for reading or writing data on the disk, a motor operable to rotate the disk at speeds greater than 7000 RPM and an actuator connected to the slider to move the slider across the disk. The trailing surface of the slider is coated with a low surface energy film to prevent build up of droplets of liquid contaminants.

Abstract: 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.
