    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.

    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: Methods of fabricating perpendicular write elements for perpendicular magnetic recording heads are discussed. In write element fabrication, write poles are fabricated according to one of many desired methods. The write poles during fabrication are typically covered by a hard mask and a photolithographic soft mask. According to the methods described herein, the soft mask is removed such as by chemical etching. The hard mask is then removed, such as by CMP and ion etching, to expose the write poles. Shield gap material may then be deposited on the write poles to define the shield gap between the write poles and the trailing shields. Trailing shield material may then be deposited on the shield gap material to form the trailing shields corresponding with the write poles.
