Easier said than done. Newer tape stock is thinner and has a different
formulation on the drive side that doesn't drive as well as the old
stuff. Our tape providers have experimented with different stock, and I
have some from a few years back that's not really playable because of the
formulation (the stock in question is no longer used for obvious reasons).
Pierre V. did an experiment once where he put something on the capstan (or
was it the pinch rollers?) that gave much more grip, but he snapped a few
tapes when they got to the end. :-) So it's a balancing act.
For the pinch rollers I tend to take off the edges and scuff them with
emery cloth, clean them, and apply CAIG rubber rejuvenator. Does it
work? Pah! Some stock still sucks. That EMI stock is no problem, and
I've even had mostly good luck with the Ampex 456 sets I have.
Martin turns his pinch rollers into tyres (tires for us American types :-)
) by really rounding off the edges. They look like what' you'd see on a
motorcycle when done.
But maybe it's not the pinch rollers but some other part of the machine
that could use adjustment in order to better drive the tapes. Keep in mind
that there's constant back tension on the tape due to the return
spring---that doesn't help.
Markus/Martin: Are you looking into the designs of your machines to drive
the newer tape formulations? It sounds like there is general satisfaction
with the way available tape stock is running, so there's no real need for a
redesign.

The tapes from the 70s do hold up really well, strangely enough. I've seen
enough sets of them. The set that I got in the Mouseotron would have been
fine except for the mouse goo all over them (and 2 tapes being spliced with
masking tape). I bet I could still clean them up and get them to play OK.
I never liked "planned obsolescence", as the Quantegy people have foisted
on their customers (reportedly) to make more money when they have to rework
archive tapes. But it is understandable that tape has a shelf life and
will eventually go downhill, just like anything else.
