Zusammenfassung:A tape drive-implemented method, according to another embodiment, includes: determining a length of a window of a servo pattern to use for calculating a lateral position estimate, determining a number of the windows of the servo pattern to use for calculating a lateral position value, receiving signals corresponding to each of the number of the windows of the servo pattern from a single servo channel, calculating a lateral position estimate for each of the number of the windows of the servo pattern, calculating the lateral position value by using the lateral position estimates, and using the lateral position value to control a tape head actuator. Other systems, methods, and computer program products are described in additional embodiments.
