Methods for selecting wrap angle for inducing tape tenting above transducer

A computer program product for determining a wrap angle, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:

• running, by the processor, a magnetic recording tape over a tape bearing surface of a module having at least one edge;
• detecting, by the processor, 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, by the processor, 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.
