Abstract
The present invention decreases the number of repositions during read back by making use of multiple read elements associated with each data track. A tape system includes a tape head with two read elements associated with each data track to be simultaneously read. Each read element generates a read signal in response to information recorded on the data track. Read electronics convert the read signal into read data. Control logic selects one of the two read elements as a source for output data for each data track. In response to a read error, output data is obtained from the other of the two read elements.
