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： A method for manufacturing a magnetic write head having a write pole with a flared step feature that defines a secondary flare point. The method involves depositing a magnetic write pole material on a substrate and then depositing a magnetic material over the write pole material followed by a non-magnetic material. A first mask is formed having a front edge to define the location of the secondary flare point, and one or more material removal processes are used to remove portions of the magnetic layer and non-magnetic layer that are not protected by this first mask. The first mask is replaced by a second mask that is configured to define a write pole, and an ion milling is performed to define the write pole. Shadowing from the magnetic layer and non-magnetic layer form a flared secondary flare point.

摘要： A method for manufacturing a magnetic write head. The write head is constructed by a method that includes depositing a magnetic write pole material and then depositing a hard mask over the magnetic material. An inorganic image transfer layer is formed over the hard mask. SiC, alumina, SiO2, SiN, Ta or TaOx. This image transfer is physically robust, so that it does not bend or tip over during manufacture. The image of a patterned photoresist layer can be transferred onto the underlying image transfer layer, and an ion milling can be performed to pattern the image of the image transfer layer onto the underlying hard mask and magnetic material, thereby forming a magnetic write pole.
