Abstract
A method of forming a hardened layer on a tape drive head assembly comprising building a tape drive head assembly, in which a number of layers of amorphous material are applied along read and write components of the tape drive head assembly as the tape drive head assembly is built and selectively heating portions of the amorphous material. A drive head assembly comprising a write component, a magnetic resistive element, and a number of layers of amorphous material, in which a portion of the amorphous material is hardened.

- in which a portion of the amorphous material is hardened.
A method of forming a tape drive head assembly comprising:
- building a tape drive head assembly, in which a number of layers of amorphous oxide material are applied along read and write components of the tape drive head assembly as the tape drive head assembly is built;
- selectively heating portions of the amorphous oxide material to form an α-phase of the oxide material;
- and
- polishing the layer of α-phase material.
