    摘要: A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method includes forming a write pole using a mask that includes a hard mask layer deposited over the write pole laminate material, and a thick, physically robust image transfer layer. The image transfer layer can be a material such as AlTiO that can be patterned by a reactive ion etching process, but which also resists deformation during processing. This process allows a write pole and wrap-around trailing shield to be constructed at very narrow track widths without the mask deformation and fencing problems experienced by prior art methods.

    摘要: A method for manufacturing a magnetic write head having a write pole with a tapered trailing edge step. The resulting tapered trailing edge step maximizes write field at very small bit sizes by preventing the magnetic saturation of the write pole at the pole tip. The method includes depositing a magnetic write pole material and then depositing a magnetic material over the magnetic write pole material. A RIE mask and hard mask are deposited over the magnetic bump material. A resist mask is formed over the RIE mask and hard mask, and a reactive ion etching is performed to transfer the pattern of the resist mask onto the underlying hard mask. Then an ion milling is performed to form a the magnetic step layer with a tapered edge that defines a tapered trailing edge step structure of the write pole.

    摘要: A method for forming a magnetic write head having a trailing shield with a tapered and stepped, self aligned trailing magnetic shield. The shield has a tapered portion that tapers away from the write pole as it extends away from the ABS. This tapered portion helps to channel flux to the pole tip portion of the shield, while preventing the loss of write field to the shield. The stepped portion of the shield further helps to prevent the loss of write field and also defines a secondary throat height of the shield that can be accurately located relative to the air bearing surface.

    摘要: The fabrication of the read head sensor components where chemical mechanical polishing (CMP) stop layer is deposited above the sensor layers, a first reactive ion etch (RIE) layer and a second RIE layer are deposited, where the second RIE layer is etchable with a different ion species than the first RIE layer. A stencil layer is then deposited and patterned to create an etching stencil having the desired magnetic read track width of the sensor. An RIE step is then conducted in which the second RIE layer is etched. An RIE step for the first RIE layer is then conducted with a different ion species. Thereafter, the sensor layers are milled where the remaining portions of the first and second RIE layers act as a milling mask. A CMP assisted liftoff step is then conducted in which the remaining portions of the ion milling mask are removed.
