Advanced Stiction-Free Slider and DLC Overcoat

摘要: The demand for higher areal densities in hard disks requires a lowering of the magnetic spacing between heads and media. To achieve this, flying height slider thickness media overcoats must be lowered. fly stably at low altitude, surface as smooth possible. However, some degree roughness is beneficial because it keeps head from adhering to disk when rest. Reducing contact area most suitable way stiction force. This can achieved by adding pads air-bearing surface, resulting what we call free (SFS). On other hand, overcoat reduced while maintaining durability anti-corrosion properties. In this paper, first focus on material tribological properties sputtered hydrogenated amorphous carbon films, which are currently used thin film Then, describe PCVD technique next generation overcoats. Finally, tetrahedral deposited filtered cathodic arc deposition, will future.
