Abstract
A servo stripe pattern for determining the longitudinal position of the tape with respect to the tape head. A data field on each frame of the servo pattern includes a digital one or a zero. An adjacent series of data fields are arranged in a predetermined sequence defining synchronization and position count fields. The position count field allows the tape controller to accurately determine where, along the length of the tape, the tape head is currently positioned.
