ABSTRACT:
A system, method and an article of manufacture to provide more accurate magnetic tape servo operation are disclosed. Accurate measurements of the width of the servo pattern written on the magnetic tape are accomplished in the presence of relatively large motion of the magnetic tape. The accurate measurements of the width of the servo pattern are used to produce a corrected position error signal that provides improved servo track following to maintain the tape head at an optimal alignment for writing and reading data tracks on the tape.
