In one embodiment, a method includes determining a distance from a to an edge closest thereto and selecting a wrap angle based on the determined distance for inducing tenting of a moving magnetic recording tape in a region above the transducer whereby a resulting tent of the moving tape extends from the edge closest thereto to a minima with a tent apex therebetween. In response to a determination to move the tape over the tape bearing surface, the method includes moving the tape over the tape bearing surface, and checking for changes in the tenting characteristics. In response to determining changes are present, the method includes sequentially selecting a different wrap angle based on the determined distance for inducing a desired tenting characteristic, and checking for changes in the tenting characteristics. Moreover, the method includes selecting a final wrap angle in response to determining no significant changes are present.
