Information about Travan
Travan is a 8 mm magnetic tape cartridge design developed by the 3M company, used for the storage of data in computer backups and mass storage. Over time, subsequent versions of Travan cartridges and drives have been developed that provide greater data capacity, while retaining the standard 8 mm width and 750' length. Travan is standardized under the QIC body.
The Travan format competes mainly against the DDS, AIT, and VXA formats.
The Travan format competes mainly against the DDS, AIT, and VXA formats.
