    摘要： A magnetic disk drive head is disclosed including a write head, which includes a P1 layer having a pedestal portion, a gap layer formed on the P1 layer, and a P2 layer formed on the gap layer. The P1 layer includes a shoulder formation having a neck portion and a beveled portion. Also disclosed is a disk drive having a write head with a P1 layer with shoulder formation, and a method for fabricating a write pole for a magnetic recording head having a P1 layer with shoulder formation.

    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.
