Abstract
Embodiments are disclosed for a method. The method includes determining a reference plane for a tape drive read-write array. The tape drive read-write array includes a first array element, a predetermined array element, and a last array element. Further, determining the reference plane is based on a first array position of the first array element and a last array position of the last array element. The method also includes capturing a position of a predetermined array element using an imaging device. The method further includes determining a deviation of the captured position from the reference plane. Additionally, the method includes generating a plot of an in-plane bow based on the deviation.
Claims20
A method comprising:
- determining a reference plane for a tape drive read-write array comprising a first array element, a predetermined array element, and a last array element, wherein determining the reference plane is based on a first array position of the first array element and a last array position of the last array element;
- capturing a position of a predetermined array element using an imaging device;
- determining a deviation of the captured position from the reference plane;
- and
- generating a plot of an in-plane bow based on the deviation.
A system comprising:
- a computer processing circuit;
- and
- a computer-readable storage medium storing instructions, which, when executed by the computer processing circuit, are configured to cause the computer processing circuit to perform a method comprising:
- determining a reference plane for a tape drive read-write array comprising a first array element, a predetermined array element, and a last array element, wherein determining the reference plane is based on a first array position of the first array element and a last array position of the last array element;
- capturing a position of a predetermined array element using an imaging device;
- determining a deviation of the captured position from the reference plane;
- and
- generating a plot of an in-plane bow based on the deviation.
A computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising instructions configured to cause one or more processors to perform a method comprising:
- determining a reference plane for a tape drive read-write array comprising a first array element, a predetermined array element, and a last array element, wherein determining the reference plane is based on a first array position of the first array element and a last array position of the last array element, wherein determining the reference plane comprises:
- capturing a first image of the first array element;
- capturing a second image of the last array element;
- overlaying the first image with the second image;
- and
- determining that the reference plane comprises the first array element and the last array element;
- capturing a position of a predetermined array element using an imaging device;
- determining a deviation of the captured position from the reference plane;
- and
- generating a plot of an in-plane bow based on the deviation.
