Here's the Webopedia definition:

Short for Digital Linear Tape, a type of magnetic tape storage device originally developed by DEC and now marketed by several companies. DLTs are ½-inch wide and the cartridges come in several sizes ranging from 20 to over 40 GB. DLT drives are faster than most other types of tape drives, achieving transfer rates of 2.5 MBps.
I could hazard a guess for what they're used for, but having never used one I don't want to steer you wrong.

Good definition. DVD tape drives have been used for years in data backup and archiving systems. They come in a variety of models - here are some - not all : DLT4000 DLT7000 DLT8000 SuperDLT. I believe that the heads are all made by Quantum. They are very reliable and fairly fast.

DLT is considered one of the most reliable tape backup mediums out there. Storage of modern drives (SuperDLT) is 110 gb uncompressed at a speed of 11 megabytes per second, and before that it was 10gb, 15gb, 20gb, 35gb, and 40gb. They come with a hefty price tag. I was lucky to grab an external 15gb and 8 tapes off eBay a while back for $250. On average, the drives alone carry a multi thousand dollar price tag.

AIT is the other popular format of tape that is used quite a bit in professional enviornments. DAT is considered low end and cheep, so it is usually not seen too much in the enterprise arena.

The reason that DVD Studio Pro recommends a DLT drive is when you are ready to have your DVD ready for replication. Instead of giving the disc duplicators a burnt DVD, instead you give them the final product on a DLT tape which is much more reliable, safe, and rugged.
