Systems and methods (e.g., 'utilities') of measuring errors in the positioning of tape head assembly data write and read elements of a tape drive and utilizing obtained calibration data to accurately align the data write elements with a desired position while writing data tracks and data read elements while reading previously written and aligned data tracks. The disclosed utilities independently determine a degree to which a tape drive write head is to be offset from a nominal write position of the write head over a tape and independently determine a degree to which a tape drive read head is to be offset from a nominal center position of previously written data track of the tape, each to collectively account for the various types of non-idealities in the write or read head of the tape drive (e.g., positioning errors between the data write/read elements and servo readers, etc.).
