I also believe the DLT is helical scan versus
CompacTape's linear scan
technology.
It's still linear. That's what the "L" in DLT stands for. For example
ECMA Standard 286 defines DLT 6 as having 208 linear tracks.
This is alleged to allow for much better tape robustness, since it doesn't
get beaten to death with every pass. This is why Seagate, HP, and IBM
have joined forces to develop a new LTO (Linear Tape Open) standard:
