Abstract
Magnetic tape media according to one embodiment includes a servo track having a plurality of servo marks therealong. A distance of the servo marks, as originally written, from an edge of the tape media varies along the length of the magnetic tape media. Magnetic tape media according to another embodiment includes a plurality of servo tracks having physical characteristics of being written by an apparatus that monitors a lateral position of the magnetic tape media passing over a servo writing head during a servo track writing operation and writes servo marks to the magnetic tape media. A timing of the writing of each servo mark is based on the monitored position of the magnetic tape media.
