I think that some Nakamichi decks are equiped with special pad lifter, so 
there is no need to worry about this.

I always liked the Nakamichi decks with the closed-loop dual capstans. One 
point of caution: closely examine the felt pressure pad that should fall 
directly over the tape and head.  In some cassettes, the glue may fail, 
causing the pad to wander off-center or fall out entirely.  In a case like 
that, put the tape in a new shell, because the misplacement or absence of 
the pressure pad will cause the tape to mistrack.

Tom, do you think that standard double capstan deks are not adequate for the 
job? I have Sony and Nakamichi decks that have closed loop dual capstan 
drives that seem to do a fairly good job, though I haven't had severely 
warped tapes that are problematic - so far!
