I suspect much less than it was for 800BPI 9 track drives.
PE (1600) and GCR (6250) are much less sensitive to head alignment.

I hadn't heard about it being a big problem for DDS though.

LTO uses servo tracks written into the tape by the manufacturer
(don't bulk erase them!) to follow the tracks. I don't know about
head azimuth for them.
