  • Publication number: 20080259498
    Abstract: A magnetic write head having independent trailing and side magnetic shields. The side shields and trailing shields are independently of one another so that they can have throat heights that are different from one another. This advantageously allows the magnetic potential between the write pole and side shields to be controlled independently of one another without relying on the side gap and trailing gap thicknesses. Furthermore, magnetic performance of the write head can be improved because the side shields can be constructed with varying tapered throat heights, while the throat height of the trailing shield can remain constant.

  • Publication number: 20080232001
    Abstract: A magnetic write head for data recording having a magnetic write pole with a stepped magnetic shell structure that defines a secondary flare point. The secondary flare point defined by the magnetic shell portion can be more tightly controlled with respect to its distance from the air bearing surface (ABS) of the write head than can a traditional flare point that is photolithographically on the main pole structure. This allows the effective flare point of the write head to be moved much closer to the ABS than would otherwise be possible using currently available tooling and photolithography techniques. The write head may also include a magnetic trailing shield that wraps around the main pole portion.
