Claims15
A linear tape head module for a linear tape drive system, the system including a tape having a data track, the module comprising:
- a substrate having a surface with a roughness;
- a thin film, having a surface with a roughness, including a data track element to at least one of read from and write to the data track;
- and
- a closure having a surface with a roughness to cap the thin film wherein the substrate, thin film, and closure surfaces cooperate to provide a tape bearing surface for the tape and wherein a roughness of a predefined portion of the tape bearing surface is less than a roughness of the tape bearing surface outside the predefined portion.
