I remember seeing, some months ago, a press release from Exabyte (I'm
on their mailing list) clarifying this issue.
The *tape transport* is 8mm format, the electronics are Exabyte's own.
I believe if you check (call Exabyte), you will find that 8mm tape
drives are written in a digital format, not some analog adaptation.
The issue of "DAT is digital, 8mm is analog" is a non-issue, probably
concocted by DAT marketing to confuse things.
If DAT is superior to 8mm, it is not because of the format.
