From: Tape

Travan is a 3M trademarked name for a new family of data minicartridge
tape media.  Travan provides additional capacity via longer
length(750' / 229 meters) and greater width(.315" / 8mm) tape then
previous generations of data minicartridge.  Drives that can
accommodate Travan cartridges must have a mechanism that can handle
wider tape (.315" / 8mm vs. earlier data minicartridge that are
.25"/6.2mm) and be able to accept the slightly larger Travan
cartridge.  All major drive manufactures have modified existing drives
or designed new mechanisms to accommodate the Travan cartridge.
Today's Travan capable minicartridge tape drive maintains the industry
standard QIC formats. These drives can write and read smaller capacity
data minicartridge tapes of the same QIC format family(See below).

Travan TR1 capable drive functionality
Cartridge 	Format		Capability	Native Capacity
DC2120		QIC-80		W/R		120MB
DC2120XL	QIC-80		W/R		170MB
QW5122F		QIC-80		W/R		208MB
TR1(Travan)	QIC-80		W/R		400MB

Travan TR3 capable drive functionality
Cartridge 	Format		Capability	Native Capacity
DC3010XL	QIC3010	              W/R		346MB
QW3010XLF	QIC3010	              W/R		425MB
DC3020XL	QIC3020	              W/R		692MB
QW3020XLF	QIC3020	              W/R		850MB
TR3(Travan)	QIC3020	              W/R		1600MB

Note

1. TR3 capable drives can read only all combinations of QIC-80 formatted
tapes
2. 3M has developed a TR2  800MB QIC3010 format tape but has not gone to
market with it at this time
3. There will be TR4 and greater media products in the future. These
products will offer greater capacity and performance.
