Abstract
According to one embodiment, a method includes running a magnetic recording tape over an edge of a tape bearing surface of a module, where the edge is proximate to a sensor of the module, detecting magnetic fields from the magnetic recording tape at different wrap angles, and selecting one of the wrap angles of the magnetic recording tape to provide about a predefined height of tenting of the magnetic recording tape above the sensor.

A method, comprising:
- running a magnetic recording tape over an edge of a tape bearing surface of a module, wherein the edge is proximate to a sensor of the module;
- detecting magnetic fields from the magnetic recording tape at different wrap angles;
- and
- selecting one of the wrap angles of the magnetic recording tape to provide about a predefined height of tenting of the magnetic recording tape above the sensor.
A computer-implemented method, comprising:
- receiving a measurement of a distance from an edge of a tape bearing surface of a module to a sensor located along the tape bearing surface of the module;
- receiving a measurement of a predefined height of tenting of a magnetic recording tape above the sensor;
- and
- calculating a wrap angle of the magnetic recording tape to achieve the predefined height of tenting when the magnetic recording tape passes over the edge.
A computer program product for determining a wrap angle to induce a desired tenting, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
- receive, by the processor, a measurement of a distance from an edge of a tape bearing surface of a module to a sensor located along the tape bearing surface of the module;
- receive, by the processor, a predefined height of tenting of a magnetic recording tape above the sensor;
- and
- calculate, by the processor, a wrap angle of the magnetic recording tape to achieve the predefined height of tenting when the magnetic recording tape passes over the edge.
