    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 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.

    摘要： Methods for forming write heads. One method includes forming a mask layer above a pole tip layer; forming a layer of resist above the mask layer; patterning the resist; removing portions of the mask layer not covered by the patterned resist; shaping a pole tip from the pole tip layer; depositing a layer of dielectric material above the pole tip and flux shaping layer, wherein the layer of dielectric material extends about adjacent to the mask layer; depositing a stop layer over the dielectric material, the stop layer abutting the mask layer; and polishing for forming a substantially planar upper surface comprising the mask layer and stop layer. Another method includes depositing a layer of dielectric material at least adjacent the pole tip, wherein the layer of dielectric material extends about adjacent to the mask layer. A further method includes forming dishing in the pole tip.

    摘要： A magnetic write head for perpendicular magnetic recording that has a write pole and a trailing or side shield that has a leading edge that extends to or beyond the leading edge of write pole, thereby ensuring complete side magnetic shielding. The write head can be formed by forming the write pole on a non-magnetic substrate that is constructed of a material that can be readily removed by reactive ion etching (RIE). The write pole can be formed by depositing a layer of magnetic write pole material over the substrate and then forming a mask over the magnetic write pole material. An ion mill can be performed to define the write pole, and then a reactive ion etch can be performed to notch the substrate, so that when a non-magnetic shield gap material is deposited it will be below or at the bottom of the write pole. Then a magnetic shield material can be deposited to form a shield having a leading edge that extends beyond the leading edge of the write pole.
