Abstract
A data storage device is disclosed comprising at least one head configured to access a magnetic tape comprising a plurality of data tracks, wherein each data track comprises a plurality of data segments and a plurality of servo sectors. The head is used to read one of the servo sectors to generate a first read signal. The first read signal is processed to generate a position error signal (PES) of the head relative to the magnetic tape, wherein the head is positioned relative to the magnetic tape based on the PES. The head is used to read one of the data segments to generate a second read signal, wherein the second read signal is processed to detect user data recorded in the data segment.
