Position error signal testing using outer edge wraps

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions readable and/or executable by a processor to cause the processor to:

• use, by the processor, formatting information which corresponds to a magnetic tape loaded in a tape drive to identify wraps on the magnetic tape, wherein identifying wraps on the magnetic tape includes:
• identifying an outermost wrap on the magnetic tape on a first side of the magnetic tape, and
• identifying an outermost wrap on the magnetic tape on a second side of the magnetic tape;
• and
• perform, by the processor, a procedure for each of the wraps identified using the formatting information, wherein performing the procedure for a given one of the wraps includes:
• sending one or more instructions to position a magnetic head of the tape drive over the given wrap, and
• collecting position error signal (PES) information which corresponds to the given wrap.

A system, comprising:

• a processor;
• and
• logic integrated with and/or executable by the processor, the logic being configured to cause the processor to:
• use, by the processor, formatting information which corresponds to a magnetic tape loaded in a tape drive to identify wraps on the magnetic tape, wherein identifying wraps on the magnetic tape includes:
• identifying an outermost wrap on the magnetic tape on a first side of the magnetic tape, and
• identifying an outermost wrap on the magnetic tape on a second side of the magnetic tape;
• and
• perform, by the processor, a procedure for each of the wraps identified using the formatting information, wherein performing the procedure for a given one of the wraps includes:
• sending one or more instructions to position a magnetic head of the tape drive over the given wrap, and
• collecting position error signal (PES) information which corresponds to the given wrap.
