Abstract
A servo track has servo pattern frames including two pairs of parallel transitions, the transitions of each pair spaced apart an equal distance, the first pair at an azimuth angle, the second pair at the opposite azimuth angle. A servo channel receives signals at first times corresponding to a servo read head detecting the transitions of the first pair of parallel transitions of a servo pattern frame, and second times corresponding to the servo read head detecting the transitions of the second pair of parallel transitions. The servo channel determines a relative lateral movement and velocity between the tape and the tape head based on respective functions of the ratio (TD−TC)/(TB−TA), distance d, and constants proportional to the azimuth angle and the trajectory angle.
