I thought 40 GB/tape (native) was the current limit for DLT? AIT claims to
do 50 GB/tape, native.

AIT came from Sony, not Exabyte. Sony claims it is an "open standard", but
right now Sony is the sole source for media and drives, I believe.
One of the neat features of AIT is that each cartridge has a 64K flash ROM
chip in it, allowing you (in theory) to store tape identification and
directory information in an instantly-accessible form. Gets rid of those
multi-hour load-and-recatalog operations. No word on how well it works in
practice, though...

Sony claims AIT puts much less tension on the tape then Exabyte's Mammoth
drives did. That was always the big problem with Exabyte's system -- the
stress their mechanism put on the tape, not the helical-scan itself. Of
course, we have to take Sony's word for it.
On other thing: I believe Quantum is the sole source for DLT. So the two
formats are equal in that department.
Each technology has a website:
http://www.dlttape.com
http://www.aittape.com
I'd take whatever they say with a grain of salt, since both are corporate
mouthpieces, but they're interesting if not unbiased.
