Abstract: A railing system with a pair of supporting posts and upper and lower rails extending between the posts includes a plurality of balusters extending between the rails. The balusters have a longitudinal axis, a curved portion and an opening extending through the baluster in a direction perpendicular to the longitudinal axis. An extension member extends through each opening in the plurality of balusters to prevent the balusters from rotating about their longitudinal axis. The openings may be asymmetrical about the longitudinal axis, with the cross-sectional dimension of the extension member corresponding to the dimensions of the openings so that the extension members may extend through the openings of a plurality of balusters only when the balusters are aligned with their curved portions in the same direction.

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.
