Tape acclimation acceleration for environmental calibration

A system, comprising:

• a processor;
• and
• logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to cause the processor to perform operations including:
• measuring a baseline servo band difference (SBD) from a beginning of a tape (BOT) to an end of the tape (EOT);
• storing values of the baseline SBD measurements in a memory;
• cycling a shorter length of the tape that is less than an entire length of the tape a plurality of times to acclimate the shorter length of the tape;
• determining a post cycling SBD of the shorter length of the tape;
• determining an acclimation change amount of the shorter length of the tape that is a difference between the baseline SBD of the shorter length of the tape and the post cycling SBD of the shorter length of the tape;
• and
• adjusting the baseline SBD values based on the determined acclimation change amount.

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

• measuring, by the controller, a baseline servo band difference (SBD) from a beginning of a tape (BOT) to an end of the tape (EOT);
• storing, by the controller, values of the baseline SBD measurements in a memory;
• cycling, by the controller, a shorter length of the tape that is less than an entire length of the tape a plurality of times to acclimate the shorter length of the tape;
• determining, by the controller, a post cycling SBD of the shorter length of the tape;
• determining, by the controller, an acclimation change amount of the shorter length of the tape that is a difference between the baseline SBD of the shorter length of the tape and the post cycling SBD of the shorter length of the tape;
• and
• adjusting, by the controller, the baseline SBD values based on the determined acclimation change amount.
