1. A method, comprising:

  • running a magnetic recording tape over a tape bearing surface of a module having at least one edge;

    detecting signals from the tape at differing wrap angles for estimating a height of tenting of the tape above a transducer at each of the wrap angles; and

    selecting a wrap angle to provide about a predefined height of tenting of the tape above the transducer whereby a resulting tent of the moving magnetic recording tape extends from the edge of the module closest thereto to a minima with a tent apex therebetween, wherein the minima is at a first point of closest approach of the moving magnetic recording tape to the tape bearing surface of the module nearest the tent apex.
