I recall the reel to reel tape recorders and also the grief on reel to reel memory tapes in the early computers. As you go to higher and higher speeds, you'll find that slipslide creep becomes harder and harder to avoid - especially at high speed direction changes in the data search on the computers.
Essentially, you're trying to improve the coefficient of friction. Until you go to mechanical interlocking (cogged belt, chain, rack and pinion) you'll only get better but you may never achieve the "nirvahnah" needed.
The challenge in ANY friction drive system is to get max traction without deteriouration in component life. CVT transmissions can be real oxymoronic in this nature as you MUST lubricate the device for it to live yet every lube used has to be used in a way so that it doesn't screw up/eliminate the friction so critical for it to transfer power from the drive to driven plate via the rolling wheel.
Mag clutches work well - 100% of the car A/C's I know of all have them.
The old Lionel trains had Magnetraction to help keep them on the track better and improve traction - dunno if it worked cause I could fly mine off at will.
The speaker magnet would help. So would pins and slots in the tape ala what they did in the old 8mm movie film. But that's essentially a chain and sprocket but it sure does keep the timing perfect.
Who'd have thunk that the nearly obsolete film product made so popular by Kodak would technology transfer to CNC so appropriately. Now, if we could only get the Stanley tape measure and the Kodak people interested in a joint venture....
Wanna bet neither would be interested???? Maybe Fuji Film and Kobe Steel. They've both done wonders with technologies that US competitors have abandoned over the years to the point that they rule the market in them, especially Kobe and the spring steel markets.
EDIT: in a final thought, check out what the bandsaw people do. They constantly have to deal with this exact same problem. Anybody who's walked a mile in their shoes would/should know the answer if anybody will. END EDIT

Reason: stunning oversight
