Abstract :
In this article, we developed a new method of measuring dynamic shear force at a high shear rate. We call this new method "fiber wobbling shear force measurement". Using this method we investigated the effect of confinement on the dynamic viscoelastic properties of perfluoropolyether (PFPE) lubricant film on a magnetic disk.
