A magnetic tape
technology developed by 3M Corporation that allows for higher data densities. Travan has been standardized by the QIC
consortium, and is backward compatible with older QIC standards. This means that Travan tape drives
can read and write older QIC tapes a well as the newer high-capacity Travan tapes. The following table shows tape capacities (uncompressed) and QIC compatibilities for the different Travan levels, 1 to 4.
