The load-dependency of the friction coefficient under a contact load in the order of sub-micronewtons was revealed. The frictional force was measured experimentally with a diamond tip of 0.1 μm radius on silicon-oxide surfaces in a laboratory atmosp

The surface roughness of four gold surfaces mechanically finished, three by diamond cutting and one by mechanical polishing, were measured with a scanning tunneling microscope (STM) and with a conventional stylus profilometer. The roughness measureme

An acoustic emission sensor is mounted on a flying slider opposed to a rotating recording medium, for example. The acoustic emission sensor outputs a detection signal in response to the sound of collision. When a protrusion exists on the recording me

A handy and precise calibration method for the displacement characteristics of a tube scanner in the submicrometer scale is proposed. A coupled-cavity laser diode sensor, which acts as a submicrometer gauge with subnanometer accuracy, is used to cali
