摘要： The invention is a magnetic transducer with separated read and write heads for perpendicular recording. The write head has a trailing shield that extends from the return pole piece toward the main pole piece to form the write gap at the air-bearing surface. One embodiment of the trailing shield is a two part structure with a pedestal and a much smaller tip that confronts the main pole piece at the gap. In one embodiment a sink of non-magnetic, electrically conductive material is disposed in the separation gap between the read head and the flux bearing pole piece. The sink is preferably made of copper and does not extend to the ABS.

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 for perpendicular magnetic recording. The method includes forming a write pole, and then depositing a refill layer. A mask structure can be formed over the writ pole and refill layer, the mask structure being configured to define a stitched pole. An ion milling or reactive ion milling can then be performed to remove portions of the refill layer that are not protected by the mask structure. Then a magnetic material can be deposited to form a stitched write pole that defines a secondary flare point. The stitched pole can also be self aligned with an electrical lapping guide in order to accurately locate the front edge of the secondary flare point relative to the air bearing surface of the write head.
