Method and system for providing a magnetic transducer having an improved hard bias seed layer

摘要

A method and system for providing a magnetic transducer is described. The method and system include providing an underlayer, a seed structure, and a magnetically hard layer. The underlayer has a surface. The seed structure resides on the surface and includes an amorphous layer and a seed layer. The amorphous layer wets the surface of the underlayer. The seed layer having a natural growth texture. The magnetically hard layer resides on the seed structure. The seed layer resides between the magnetically hard layer and the amorphous layer. The magnetically hard layer has a desired crystal orientation corresponding to the natural growth texture of the seed layer.

1. A magnetic transducer comprising:
an underlayer having a top surface; a magnetoresistive sensor residing on a first portion of the top surface; a seed structure on a second portion of the top surface, the seed structure including an amorphous layer and a seed layer, the amorphous layer wetting the second portion of the top surface of the underlayer, the seed layer having a natural growth texture, no portion of the seed structure residing between the underlayer and the magnetoresistive sensor such that no portion of the amorphous layer and no portion of the seed layer are between the underlayer and the magnetoresistive sensor; and a magnetically hard layer on the seed structure, the seed layer residing between the magnetically hard layer and the amorphous layer, the magnetically hard layer having a desired crystal orientation corresponding to the natural growth texture of the seed layer.
