Abstract
According to one embodiment, a method includes determining a first distance from a sensor to a first edge closest thereto, where the sensor is positioned between a lower shield and the first edge, selecting a first wrap angle based on the first distance for inducing tenting of a moving magnetic recording tape in a region above the sensor, determining a second distance from a second edge to the sensor, and selecting a second wrap angle based on the determined second distance for affecting or not affecting the tenting of a moving magnetic recording tape in the region above the sensor.
Claims17
A method comprising:
- determining a first distance from a sensor to a first edge closest thereto, wherein the sensor is positioned between a lower shield and the first edge;
- selecting a first wrap angle based on the first distance for inducing tenting of a moving magnetic recording tape in a region above the sensor;
- determining a second distance from a second edge to the sensor;
- and
- selecting a second wrap angle based on the determined second distance for affecting or not affecting the tenting of a moving magnetic recording tape in the region above the sensor.
A method comprising:
- running a magnetic recording tape over an edge proximate to a sensor of a module;
- detecting magnetic fields from the magnetic recording tape;
- and
- selecting a wrap angle to provide about a predefined height of tenting of the magnetic recording tape above the sensor as determined using the detected magnetic fields.
A computer-implemented method, comprising:
- receiving a measurement of a first distance from a first edge to a sensor;
- receiving a predefined height of tenting of a magnetic recording tape above the sensor;
- and
- calculating a wrap angle to create the predefined height of tenting when the magnetic recording tape passes over the first edge in a direction of tape travel.
