Calibration of high-density servo pattern detector parameters

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to:

• cause, by the processor, a servo reader to move in a first direction over a high-density servo pattern which includes a plurality of high-density servo tracks, wherein each of the servo tracks includes at least two patterns written at different frequencies to produce different periodic waveforms during readback;
• receive, by the processor, a readback signal from the servo reader as the servo reader moves in the first direction;
• and
• use, by the processor, the readback signal to set a gain parameter for each of the respective periodic waveforms.

A tape drive, comprising:

• a controller comprising logic integrated with and/or executable by the controller to cause the controller to:
• cause a servo reader to move in a first direction over a high-density servo pattern which includes a plurality of high-density servo tracks, wherein each of the servo tracks includes at least two patterns written at different frequencies to produce different periodic waveforms during readback;
• receive a readback signal from the servo reader as the servo reader moves in the first direction;
• and
• use the readback signal to set a gain parameter for each of the respective periodic waveforms.
