    摘要： A magnetic head for use in a perpendicular recording system having a novel shield structure that provides exceptional magnetic shielding from extraneous magnetic fields such as from a write coil, shaping layer or return pole of the write head. The shield structure is constructed to have a bottom or leading surface that is generally coplanar with the bottom or leading surface of the shaping layer, but all or a portion of the shield structure is not as thick as the shaping layer so as to have a top surface that does not extend to the same elevation (in a trailing direction) as that of the shaping layer. Making the shields extend to a lower level than the shaping layer improves magnetic performance by reducing flux leakage from the write pole, and also provides manufacturing advantages, such as during the manufacturing of the write pole. These manufacturing advantages include the advantage of having the shields covered with a protective layer of, for example, alumina during the ion milling of the write pole.

    摘要： A magnetic write head for perpendicular magnetic recording. The write head has a secondary flare point defined by magnetic structures that extend from the sides of the write pole, but not over the trailing edge of the write pole. The magnetic structures each have a front edge that defines the secondary flare point. By constructing the magnetic structures so that they only extend from the sides of the write pole and not over the write pole, they can be formed by electroplating, while leafing the mask structure (used to define the write pole) still intact, thereby greatly simplifying manufacture and preventing damage to the write pole during manufacture.

    摘要： A perpendicular recording write head has ferromagnetic first and second pole pieces which are connected at a back gap and an insulation stack with a write coil layer embedded therein is located between the first and second pole pieces and between a head surface of the write head and the back gap. The second pole piece has a pole tip which is located at the head surface and a recessed ferromagnetic write shield layer. A nonmagnetic isolation layer is located between the second pole piece and the write shield layer and at least one ferromagnetic stud is magnetically connected between the first pole piece layer and the write shield layer and is located between the head surface and the insulation stack.
