Abstract:
1. Method for operating a storage device with a tape (TP) and a head (HU) wherein the head (HU) comprises a first read element (RE 1 ) and a second read element (RE 2 ), wherein each read element (RE 1 , RE 2 ) is operable to detect predetermined servo patterns of a particular predetermined servo band (SP) being stored on the tape (TP) along a longitudinal expansion of the tape (TP), wherein the first and the second read element (RE 1 , RE 2 ) are arranged in such a way, that the tape (TP) at first passes one of both read elements (RE 1 , RE 2 ) and subsequently passes the other of both read elements (RE 1 , RE 2 ) when the tape (TP) moves in a predetermined longitudinal direction (X), wherein a tape transport direction (TPDIR) of the tape (TP) along the longitudinal direction (X) is determined, the first read element (RE a position error signal (PES an estimated lateral track position (d with respect to the predetermined reference point (REF) another estimated lateral track position (d* a control signal (u) is determined dependent on the other estimated lateral track position (d*
