Abstract
A method and system for reading data containing errors due to curved or displaced tracks in a track region reproduced by reproducing heads in a tape drive includes a signal processing circuit for sensing a first set of parameters associated with the data at a first head position at predetermined points along each track in the region. The signal processing circuit also senses a second set of parameters associated with the data at a second head position different from the first head position at the predetermined points along each track in the region. A movable head controller positions the reproducing heads to follow the curved or displaced tracks based on the first and second head positions and the first and second set of parameters.
