An arrangement and method for compensating for the written-in tracking error
for
a linear tape drive filters out spatial error components of a position error signal
(PES). The position information contained within A, B pairs of servo stripes, and
within C, D pairs of stripes is preserved. The timing between the A and C bursts
and the C and A bursts is filtered, such as by low pass filtering, to filter out
the error that can be written-in by a servo writer. The timing signal for the A,
B bursts and C, D bursts are divided by the filtered timing signals for the AC
and CA timing signals, respectively. This ratio provides the filtered PES signal
used by a head positioner to precisely position the head with respect to the tape.
