Abstract
The present invention decreases the number of repositions during read back by making use of multiple read elements associated with each data track. Each of a plurality of sets of read electronics receives the read signal from either one or the other of the two read elements associated with each data track and converts the received read signal into read data. For each data track, control logic selects one of the two read elements as a source for output data. In response to a determination that a read error has occurred, the control logic selects the other of the two read elements as the source for output data. For each data track, one read element is offset relative to the other read element in an offset direction normal to the tape direction.
