Abstract
Embodiments include methods, systems and computer program products for controlling a lateral position of a tape head of a magnetic tape drive. Aspects include determining a first servo signal by reading position marks from a first servo band on a magnetic tape using a first sensor and determining a second servo signal by reading position marks from a second servo band on the magnetic tape using a second sensor. Aspects also include delaying the first servo signal relative to the second servo signal by a delay and calculating an average signal based on the first and the delayed second servo signal. Aspects further include determining servo information from the average signal indicative of a deviation of the lateral position of the tape head from an ideal lateral position of the tape head and controlling the tape head to adjust its lateral position such that the deviation is decreased.
