An assembly, apparatus and method for fabricating a structural element of a hard disk drive air bearing. The method and apparatus provide an improved protective layer, an improved structural element consisting of a single layer of structural material, and a method consisting of applying the improved protective layer, applying a uniform layer of structural material, applying a resist layer, etching the structural material layer, and removing the resist layer.
摘要:
A disk drive thin-film write head structure has a pole tip structure with reduced susceptibility to corrosion. The write head has a first ferromagnetic pole tip that includes a pedestal pole layer and a capping layer on the pedestal pole layer. The capping layer has an extension and the write gap is located between the capping layer extension and the second pole tip. Substantially the entire thickness of the pedestal pole layer is formed of a lower-moment alloy and the capping layer is formed of a higher-moment alloy and is made thick enough to compensate for the lower-moment alloy in the pedestal pole layer. The pedestal pole layer may be a bilayer of two different alloys with the upper layer in the bilayer having a higher moment. The width of the pedestal pole layer is substantially reduced to reduce the pole tip area exposed. The reduced pole tip area and the increased use of lower-moment alloys enable a thinner protective film to be used to protect the pole tips from corrosion.
摘要:
A method for applying a protective layer to an electronic device such as the ABS of a slider, magnetic head, etc. for reducing paramagnetic deadlayer thickness includes selecting an etching angle for minimizing formation of a paramagnetic deadlayer at an interface of an electronic device and an adhesive layer subsequently formed on the electronic device, etching a surface of an electronic device at the selected angle, the selected angle being less than about 75 degrees from an imaginary line extending perpendicular to the surface, forming an adhesive layer on the etched surface of the electronic device, and forming a protective layer on the adhesive layer. A magnetic head formed by the process is also disclosed.
