What Makes DLTtape Cartridges Better?
For many DLTtape system users, the biggest difference between the
DLTtape system and other tape systems has nothing to do with trans-
fer speed and cartridge capacity. It has everything to do with confi-
dence that the information they put on a DLTtape cartridge two
years ago is going to be accessible with DLTtape drives they might
buy two years from now. With other tape technologies, this level of
media compatibility across generations has not been the case. Figure
7-1 shows which models of DLTtape cartridges are compatible with
which models of DLTtape drives.
