1. A module, comprising:
- a plurality of transducers selected from a group consisting of data readers, servo readers, and data writers;
a tape bearing surface having a transducer region aligned with the transducers in a tape travel direction, and outer regions flanking the transducer region in a direction perpendicular to the tape travel direction;
a first coating on the transducer region of the tape bearing surface; and
a second coating on at least one of the outer regions of the tape bearing surface, the second coating being different than the first coating,wherein the first coating is also present on at least one of the outer regions of the tape bearing surface.
