ABSTRACT:
A linear tape system has a tape head to read and write a linear data storage tape. As the tape moves in a longitudinal direction, the tape head senses magnetic transition stripes in longitudinal servo bands to control the lateral position of the tape head relative to the tape. The system is equipped with a linear speed calculating unit that derives timing data from the servo band stripes and computes a linear speed of the data storage tape in the longitudinal direction. The linear speed calculation produces a result that is independent of the lateral position of the tape head relative to the tape.
