摘要:
A servo track configuration includes at least one servo track having a width. A servo pattern is repeatedly recorded in the at least one servo track. Repeatedly recording the servo pattern includes repeating the simultaneous recording of first and second reference pattern lines and a track pattern line in the at least one servo track. Each of the first and second reference pattern lines has an identical predetermined geometry and extends across the width of the at least one servo track. Further, the track pattern line has a predetermined geometry that is different than the predetermined geometry of the first and second reference pattern lines and extends across the width of the at least one servo track.
