ABSTRACT:
Accurate tape servo track following is achieved by sampling servo edges at tape head alignments established with non-servo information, and processing the samples to (1) estimate optimal tape head index positioning to best align data as well as servo components, and (2) provide corrected position error signals (PESs) including a calculated error for comparison during ongoing servo track following to maintain the tape head at an optimal alignment for accurate alignment with the servo edges as well as data tracks on the tape.
