  • Patent number: 8815060
    Abstract: 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.

  • Patent number: 7835111
    Abstract: A magnetic write head for perpendicular magnetic recording that is resistant to write pole and trailing shield protrusion. The write pole includes a magnetic return pole that is magnetically connected with the trailing shield, the return pole being resistant to deformation or recession such as from mechanically abrasive slider cleaning operations such as soda blast.

  • Patent number: 7339763
    Abstract: A disk drive thin-film write head has a first ferromagnetic pole tip that includes a pedestal pole layer and a capping layer on the pedestal pole layer. A substantial portion 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 NiFe alloys with the upper layer in the bilayer having a higher moment, and the capping layer may be a CoFe alloy. 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.
