Abstract
In our previous study, we have developed a highly-sensitive shear force measuring method, which we called the "fiber wobbling method". This method enabled us to measure the viscoelastic properties of molecularly thin lubricant films. However, the shearing speeds were around a few hundred μm/s and these were quite slower than those supposed in the head-disk interface. In this study, we aimed to achieve higher shearing speed in the fiber wobbling method.
