Method and system for providing an improved hard bias structure

A disk drive including a magnetic head comprising:

• a seed layer for a hard bias layer, the seed layer having a seed layer lattice constant and a natural growth texture, wherein the seed layer comprises a first deposition gas configured to expand the lattice of the seed layer;
• a hard bias structure on the seed layer, the hard bias structure including a hard bias layer on the seed layer, the natural growth texture corresponding to a texture for the hard bias layer, the hard bias layer having a bulk lattice constant and including a second deposition gas therein, the first deposition gas being lighter than the second gas;
• wherein the seed layer lattice constant is less than the bulk lattice constant, and wherein the disk drive is configured to obtain information from a magnetic media using the magnetic head.
