Bilayer carbon overcoating for magnetic data storage disks and magnetic head/slider constructions |
摘要 |
A magnetic head/slider construction and a magnetic data recording disk, as well as a method for fabricating the magnetic head/slider construction and the magnetic data storage disk. To practice the method, there is formed over the air bearing surface of each of a magnetic head/slider construction and a magnetic data storage disk a wear resistant carbon layer. Over each of the wear resistant carbon layers is then formed a lubricating carbon layer. The lubricating carbon layers may be formed in-situ upon the wear resistant carbon layers. The wear resistant carbon layers may be formed from nitrogenated wear resistant carbon materials having a nitrogen content of from about 15 to about 30 atomic percent and hydrogenated wear resistant carbon materials having a hydrogen content of from about 15 to about 25 atomic percent. The lubricating carbon layer is preferably formed from a hydrogenated lubricating carbon material having a hydrogen content of from about 30 to about 40 atomic percent. Through the method, there is formed magnetic head/slider constructions and magnetic data recording disks simultaneously possessing improved wear resistance characteristics and improved lubricating properties.
